467 A pole placement controller for non-linear dynamic plantsQ M Zhu*and L Z GuoFaculty of Computing,Engineering and Mathematical Sciences,University of the West of England,Bristol,UKAbstract:In this study a control-oriented model is proposed to represent a wide range of non-linear discrete-time dynamic plants.As a testimony to the e ciency of the model structure forcontrol system design,a pole placement controller is designed for non-linear discrete-time plants.Mathematically the solution of the controller output is converted into resolving a polynomial equationin the current control term u(t),which signi cantly reduces the di culties encountered in non-linearcontrol system synthesis and computational complexities.The integrated procedure provides astraightforward methodology to use in linear control system design techniques when designing non-linear control systems.For a demonstration of the e ectiveness of the proposed methodology usedto deal with practical problems,pole placement controllers are designed for three non-linear plants,including the Hammerstein model,a laboratory-scale liquid level system and a continuous stirredtank reactor.The simulation results are presented

[12,13],in this study a control-oriented model cedure is applicable for arbitrary known plant delay as well.Leontarities and Billings [15]have shown that such structure is proposed to represent a

presented to provide a straight-forward methodology to design non-linear control bilinear and several other well-known linear and non-linear model sets can be shown to be special classes systems by using linear control system design techniques.The proposed model can be explained as an expansion of the NARMAX model.With its generality,the di -culty occurs when controlling a plant based on the of the plant output according to its current control term u (t )and therefore the input /output behaviour of the NARMAX model is considered because of the lack of a manoeuvrable structure.Therefore various possibilities plant is described by a power series of u (t ).This is a quite general modelling framework because many non-for parameterizing f (·)exist,including the extended model set NARMAX

polynomial with respect to u (t 1)as follows:those controller design methodologies derived from linear plants can be conveniently extended to design non-linear discrete-time systems.Furthermore,since the y (t )=Mj =0a j (t )u j (t 1)(2)model structure exhibits a polynomial structure in the current control u (t ),there is only a need to solve a poly-where M is the degree of model input u (t

摄影：水镜应邀和鹭佳兄一起到厦门软件学院,为集美大学
城各校一百多余名学生代表做一个关于青春记忆的漫谈，这是“寻·厦门征文、摄影大赛”系列活动的压轴戏。

虽说“好汉不提当年勇”，但我在大学读书时可是民选的“团小组长”，既然活动是团市委参与主办的，说说当年我们厦大男生的奇闻逸事应该是有声有色的，人家这么多学生在假日冒雨来听你的说话，如果只说套话和大话，岂不苦闷人家也羞辱自我。

鹭佳和我“一镜一动”，可谓博客之风图文并茂，现场的男生女生鼓掌时面露轻松的笑容，在这个惜别台风湿度很大水雾很浓的下午，轻松是心境的一种快慰！
出场时发现“学生记者团”的一张简易的欢迎海报，米黄色的纸张，言简意赅的文字，清新脱俗，美不胜收，让我开心得厚起脸皮与之合影：这就是学生，这才是学生，谢谢“学生记者团”，“厦大学生会老记者郑启五向你报到！”2011/6/11

These components are assembled in a compact (38 mm x 10 mm) plastic package.Individual LED dot addressablity allows the user great freedom in creating special characters or mini-icons. The User DefinableCharacter Set Examples illustrate 200 different character and sym-bol possibilities.The use of a serial data interface provides a highly efficient inter-connection between the display and the mother board. TheSCD558X requires only 4 lines as compared to 15 for an equiva-lent 8 character parallel input part.The on-board CMOS IC is the electronic heart of the display. The IC accepts decoded serial data, which is stored in the internal RAM. Asynchronously the RAM is read by the character multiplexer at a strobe rate that results in a flicker free display. Figure …SCD558X Block Diagram“ (page 7) shows the three functional areas of the IC. These include: the input serial data register and control logic, a 200 bits two port RAM, and an internal multiplexer/display driver.Display Column and Row FormatC0C1C2C3C4Row 011111Row 100100Row 200100Row 300100Row 411= Display dot …ON“ 0=Display dot …OFF“Column Data RangesRow 000H to 1FH Row 120H to 3FH Row 240H to 5FH Row 360H to 7FH Row 480H to 9FH2006-01-238The following explains how to format the serial data to be loaded into the display. The user supplies a string of bit mapped decoded characters. The contents of this string is shown in Figure …Loading Serial Character Data a“ (page 8). Figure …Loading Serial Charac-ter Data b“ (page 8) shows that each character consist of six 8 bit words. The first word encodes the display character location and the succeeding five bytes are row data. The row data represents the status (On, Off) of individual column LEDs. Figure …Loading Serial Character Data c“ (page 8) shows that each 8 bit word is formatted to include a three bit Operational Code (OPCODE)defined by bits D7–D5 and five bits (D4–D0) representing Column Data, Character Address, or Control Word Data.Figure …Loading Serial Character Data d“ (page 8) shows thesequence for loading the bytes of data. Bringing the LOAD line low enables the serial register to accept data. The shift action occurs on the low to high transition of the serial data clock (SDCLK). The least significant bit (D0) is loaded first. After eight clock pulses the LOAD line is brought high. With this transition the OPCODE is decoded. The decoded OPCODE directs D4–D0 to be latched in the Character Address register, stored in the RAM as Column data, or latched in the Control Word register. The control ICrequires a minimum 600 ns delay between successive byte loads. As indicated in Figure …Loading Serial Character Data a“ (page 8), a total of 528 bits of data are required to load all eight characters into the display.The Character Address Register bits, D4–D0 (T able …Load Charac-ter Address“ (page 9)) and Row Address Register bits, D7–D5 (T able …Load Column Data“ (page 9)) direct the Column Data bits, D4–D0 (T able …Load Column Data“ (page 9)) to specific RAM loca-tion. T able …Character ’D’“ (page 8) shows the Row Address for the example character “D.” Column data is written and read asynchro-nously from the 200 bit RAM. Once loaded the internal oscillator and character multiplexer reads the data from the RAM. These characters are row strobed with column data as shown in Figures …Row and Column Location“ (page 9) and …Row Strobing“(page 10). The character strobe rate is determined by the internal or user supplied external MUX Clock and the IC’s ÷320 counter.Character “D”Op code D7D6 D5Column Data D4D3D2D1D0 C0C1C2C3C4HexRow 0000111101E Row 10011000131Row 20101000151Row 3011 1000171Row 4111119EThe user can activate four Control functions. These include: LED Brightness Level, Lamp T est, IC Power Down, or Display Clear. OPCODEs and five bit words are used to initiate these functions. The OPCODEs and Control Words for the Character Address and Loading Column Data are shown in T ables …Load Character Address“ (page 9) and …Load Column Data“ (page 9).The user can select seven specific LED brightness levels, T able …Display Brightness“ (page 9). These brightness levels (in percent-ages of full brightness of the display) include: 100% (F0 HEX), 53% (F1HEX), 40% (F2HEX), 27% (F3HEX), 20% (F4HEX), 13% (F5HEX), and 6.6% (F6HEX). The brightness levels are controlled by chang-ing the duty factor of the row strobe pulse.The SCD558XA offers a unique Display Power Down feature which reduces I CC to less than 50 µA. When FF HEX is loaded, as shown in Table …Power Down“ (page 9), the display is set to 0% brightness and the internal multiplex clock is stopped. When in the Power Down mode data may still be written into the RAM. The display is reactivated by loading a new Brightness Level Control Word into the display.The Lamp T est is enabled by loading F8 HEX, T able …Lamp T est“ (page 9), into the serial shift register. This Control Word sets all of the LEDs to a 53% brightness level. Operation of the Lamp T est has no affect on the RAM and is cleared by loading a Brightness Control Word.The Software Clear (C0HEX), given in T able …Software Clear“ (page 9), clears the Address Register and the RAM. The display is blanked and the Character Address Register will be set to Charac-ter 0. The internal counter and the Control Word Register are unaf-fected. The Software Clear will remain active until the next data input cycle is initiated.Load Character AddressOp codeD7D6 D5Character AddressD4D3D2D1D0Hex OperationLoad10100000A0Character 0 10100001A1Character 1 10100010A2Character 2 10100011A3Character 3 10100100A4Character 4 10100101A5Character 5 10100110A6Character 6 10100111A7Character 7 Load Column DataOp codeD7D6 D5Column DataD4D3D2D1D0Operation Load000C0C1C2C3C4Row 0 001C0C1C2C3C4Row 1 010C0C1C2C3C4Row 2 011C0C1C2C3C4Row 3 100C0C1C2C3C4Row 4Display BrightnessOp codeD7D6 D5Control WordD4D3D2D1D0Hex OperationLevel 11110000F0100% 11110001F153% 11110010F240% 11110011F327% 11110100F420% 11110101F513% 11110110F6 6.6%Power DownOp codeD7D6 D5Control WordD4D3D2D1D0Hex OperationLevel 11111111FF0%brightnessLamp TestOp codeD7D6 D5Control WordD4D3D2D1D0Hex OperationLevel 11110B B B Lamp Test(OFF) 11111001F8Lamp Test(OFF)Software ClearOp codeD7D6 D5Control WordD4D3D2D1D0Hex OperationLevel 11000000C0CLEAR2006-01-239Row StrobingMultiplexer and Display DriverThe eight characters are row multiplexed with RAM resident col-umn data. The strobe rate is established by the internal or external MUX Clock rate. The MUX Clock frequency is divided by a 320 counter chain. This results in a typical strobe rate of 750 Hz. By pulling the Clock SEL line low, the display can be operated from an external MUX Clock. The external clock is attached to the CLK I/O connection (pin 15). The maximum external MUX Clock frequency should be limited to 1.0 MHz.An asynchronous hardware Reset (pin 13) is also provided. Bring-ing this pin low will clear the Character Address Register, Control Word Register, RAM, and blanks the display. This action leaves the display set at Character Address 0, and the Brightness Level set at 100%.Thermal ConsiderationsThe SCD558XA has been designed to provide lowest thermal resistance from the CMOS to the ground pin.The heat is then conducted through the traces on the users circuit board to free air. The max. IC operating temperature is 125°C. Maximum. IC junction temperature is calculated using the following equation:T J (IC) Max.=T A+(P D Max.) (RθJ-PIN+RθPIN-A)where RθJ-PIN=35°C/W.P D Max.=V CC Max.x I CC Max=5.5 Vx0.240=1.32 W.RθPIN-A will depend on ground trace thickness, whether parts are soldered to the pcb or socketed and on air circulation.Electrical & Mechanical ConsiderationsInterconnect ConsiderationsOptimum product performance can be had when the following electrical and mechanical recommendations are adopted. The SCD558XA’s IC is constructed in a high speed CMOS process, consequently high speed noise on the SERIAL DAT A, SERIAL DAT A CLOCK, LOAD and RESET lines may cause incorrect data to be written into the serial shift register. Adhere to transmission line termination procedures when using fast line drivers and long cables (>10 cm).Good digital grounds (pins 14, 28) and power supply decoupling (pins 6, 9, 20, 23) will insure that I CC (<400 mA peak) switching currents do not generate localized ground bounce. Therefore it is recommended that each display package use a 0.1 µF and 20 µF capacitor between V CC and ground.When the internal MUX Clock is being used connect the CLKSEL pin to V CC. In those applications where RESET will not be con-nected to the system’s reset control, it is recommended that this pin be connected to the center node of a series 0.1 µF and 100 kΩRC network. Thus upon initial power up the RESET will be held low for 10 ms allowing adequate time for the system power supply to stabilize.ESD ProtectionThe input protection structure of the SCD558XA provides signifi-cant protection against ESD damage. It is capable of withstanding discharges greater than 2.0 kV. T ake all the standard precautions, normal for CMOS components. These include properly grounding personnel, tools, tables, and transport carriers that come in contact with unshielded parts. If these conditions are not, or cannot be met, keep the leads of the device shorted together or the parts in anti-static packaging.Soldering ConsiderationsThe SCD558XA can be hand soldered with SN63 solder using a grounded iron set to 260°C.Wave soldering is also possible following these conditions: Pre-heat that does not exceed 93°C on the solder side of the PC board or a package surface temperature of 85°C. Water soluble organic acid flux (except carboxylic acid) or rosin-based RMA flux without alcohol can be used.Wave temperature of 245°C ± 5°C with a dwell between 1.5 sec. to 3.0 sec. Exposure to the wave should not exceed temperatures above 260°C for five seconds at 1.59 mm (0.063") below the seat-ing plane. The packages should not be immersed in the wave. Post Solder Cleaning ProceduresThe least offensive cleaning solution is hot D.I. water (60 °C) for less than 15 minutes. Addition of mild saponifiers is acceptable. Do not use commercial dishwasher detergents.For faster cleaning, solvents may be used. Exercise care in choos-ing solvents as some may chemically attack the nylon package. Maximum exposure should not exceed two minutes at elevated tem-peratures. Acceptable solvents are TF (trichlorotrifluorethane), T A, 111 T richloroethane, and unheated acetone.(1)Note:1)Acceptable commercial solvents are: Basic TF, Arklone, P.Genesolv, D. Genesolv DA, Blaco-T ron TF and Blaco-T ron T A.2006-01-2310Unacceptable solvents contain alcohol, methanol, methylene chloride, ethanol, TP35, TCM, TMC, TMS+, TE, or TES. Since many commercial mixtures exist, contact a solvent vendor for chemical composition information. Some major solvent manufac-turers are: Allied Chemical Corporation, Specialty Chemical Divi-sion, Morristown, NJ; Baron-Blakeslee, Chicago, IL; Dow Chemical, Midland, MI; E.I. DuPont de Nemours & Co., Wilming-ton, DE.For further information refer to Appnotes 18 and 19 atAn alternative to soldering and cleaning the display modules is to use sockets. Naturally, 28 pin DIP sockets 7.62 mm (0.300") wide with 2.54 mm (0.100") centers work well for single displays. Multi-ple display assemblies are best handled by longer SIP sockets or DIP sockets when available for uniform package alignment. Socket manufacturers are Aries Electronics, Inc., Frenchtown, NJ; Garry Manufacturing, New Brunswick, NJ; Robinson-Nugent, New Albany, IN; and Samtec Electronic Hardward, New Albany, IN.For further information refer to Appnote 22 at Optical ConsiderationsThe 3.68 mm (0.145") high character of the SCD558XA gives readability up to eight feet. Proper filter selection enhances read-ability over this distance.Using filters emphasizes the contrast ratio between a lit LED and the character background. This will increase the discrimination of different characters. The only limitation is cost. T ake into consider-ation the ambient lighting environment for the best cost/benefit ratio for filters.Incandescent (with almost no green) or fluorescent (with almost no red) lights do not have the flat spectral response of sunlight. Plas-tic band-pass filters are an inexpensive and effective way to strengthen contrast ratios. The SCD558XA are red/super-red dis-plays and should be matched with long wavelength pass filter in the 570 nm to 590 nm range. The SCD558XA should be matched with a yellow-green band-pass filter that peaks at 565 nm. For dis-plays of multiple colors, neutral density grey filters offer the best compromise.Additional contrast enhancement is gained by shading the dis-plays. Plastic band-pass filters with built-in louvers offer the next step up in contrast improvement. Plastic filters can be improved further with anti-reflective coatings to reduce glare. The trade-off is fuzzy characters. Mounting the filters close to the display reduces this effect. Take care not to overheat the plastic filter by allowing for proper air flow.Optimal filter enhancements are gained by using circular polarized, anti-reflective, band-pass filters. The circular polarizing further enhances contrast by reducing the light that travels through the fil-ter and reflects back off the display to less than 1%.Several filter manufacturers supply quality filter materials. Some of them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homa-lite, Wilmington, DE; 3M Company, Visual Products Division, St. Paul, MN; Polaroid Corporation, Polarizer Division, Cambridge, MA; Marks Polarized Corporation, Deer Park, NY, Hoya Optics, Inc., Fremont, CA.One last note on mounting filters: recessing displays and bezel assemblies is an inexpensive way to provide a shading effect in overhead lighting situations. Several Bezel manufacturers are: R.M.F. Products, Batavia, IL; Nobex Components, Griffith Plastic Corp., Burlingame, CA; Photo Chemical Products of California, Santa Monica, CA; I.E.E.–Atlas, Van Nuys, CA.Microprocessor InterfaceThe microprocessor interface is through the serial port, SPI port or one out of eight data bits on the eight bit parallel port and also con-trol lines SDCLK and LOAD.Power Up SequenceUpon power up display will come on at random. Thus the display should be reset at power-up. The reset will set the Address Regis-ter to Digit 0, User RAM is set to 0 (display blank) the Control Word is set to 0 (100% brightness with Lamp T est off) and the internal counters are reset.2006-01-23112006-01-2312Cascading Multiple DisplaysMultiple displays can be cascaded using the CLKSEL and CLK I/O pins as shown below. The display designated as the Master Clock source should have its CLKSEL pin tied high and the slaves should have their CLKSEL pins tied low. All CLK I/O pins should be tied together. One display CLK I/O can drive 15 slave CLK I/Os. Use RST to synchronize all display counters.Loading Data Into the DisplayUse following procedure to load data into the display:1.Power up the display.2.Bring RST low (600 ns duration minimum) to clear the Multiplex Counter, Address Register, Control Word Register,User Ram and Data Register. The display will be blank. Display brightness is set to 100%.3. If a different brightness is desired, load the proper brightness opcode into the Control Word Register.4. Load the Digit Address into the display.5. Load display row and column data for the selected digit.6. Repeat steps 4 and 5 for all digits.2006-01-2313Data Contents for the Word “Displays”Step D7D6D5D4D3D2D1D0FunctionAB (optional) 1101110000010B B BCLEARBRIGHTNESS SELECT1 2 3 4 5 6101000001010011100100001111010001100011000111110DIGIT D0 SELECTROW 0 D0 (D)ROW 1 D0 (D)ROW 2 D0 (D)ROW 3 D0 (D)ROW 4 D0 (D)7 8 9 10 11 12101000001010011100100010111000100001000010001110DIGIT D1 SELECTROW 0 D1 (I)ROW 1 D1 (I)ROW 2 D1 (I)ROW 3 D1 (I)ROW 4 D1 (I)13 14 15 16 17 18101000001010011100100100111110000011100000111110DIGIT D2 SELECTROW 0 D2 (S)ROW 1 D2 (S)ROW 2 D2 (S)ROW 3 D2 (S)ROW 4 D2 (S)19 20 21 22 23 24101000001010011100100111111010001111101000010000DIGIT D3 SELECTROW 0 D3 (P)ROW 1 D3 (P)ROW 2 D3 (P)ROW 3 D3 (P)ROW 4 D3 (P)25 26 27 28 29 30101000001010011100101001000010000100001000011111DIGIT D4 SELECTROW 0 D4 (L)ROW 1 D4 (L)ROW 2 D4 (L)ROW 3 D4 (L)ROW 4 D4 (L)31 32 33 34 35 36101000001010011100101010010001010111111000110001DIGIT D5 SELECTROW 0 D5 (A)ROW 1 D5 (A)ROW 2 D5 (A)ROW 3 D5 (A)ROW 4 D5 (A)37 38 39 40 41 42101000001010011100101101000101010001000010000100DIGIT D6 SELECTROW 0 D6 (Y)ROW 1 D6 (Y)ROW 2 D6 (Y)ROW 3 D6 (Y)ROW 4 D6 (Y)43 44 45 46 47 48101000001010011100101110111110000011100000111110DIGIT D7 SELECTROW 0 D7 (S)ROW 1 D7 (S)ROW 2 D7 (S)ROW 3 D7 (S)ROW 4 D7 (S)Note:If the display is already reset at Power Up, there is no need for Software Clear.2006-01-2314User Definable Character Set Examples*Upper and Lower Case AlphabetsNumerals and Punctuation*CAUTION: No more than 128 LEDs “on” at one time at 100% brightness. 2006-01-2315User Definable Character Set Examples* (continued) Scientific Notations, etc.Foreign Characters*CAUTION: No more than 128 LEDs “on” at one time at 100% brightness.2006-01-23162006-01-2317P ublished byOSRAM Opto Semiconductors GmbHWernerwerkstrasse 2, D-93049 Regensburg © All Rights Reserved.Attention please!The information describes the type of component and shall not be considered as assured characteristics.Terms of delivery and rights to change design reserved.
