IRMCK171 is designed to achieve low cost yet high performance control solutions for advanced inverterized appliance motor control. IRMCK171 contains two computation engines. One is the Flexible Motion Control Engine (MCE TM) for sensorless control of permanent magnet motors or induction motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The MCE TM contains a collection of control elements implemented in a dedicated computation engine such as Vector rotator, Arc-Tangent, Multiply/Divide, Low loss SVPWM and Motor current sensing. The user can program a motion control algorithm by connecting Control elements using a graphic compiler. Key components of the complex sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks. A unique analog/digital circuit and algorithm to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle instruction execution (16.5MIPS at 33MHz 8051CLK). The MCE and 8051 microcontroller communicate via dual port RAM for signal monitoring and command input. An advanced graphic compiler for the MCE TM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG-based emulator tools are supported for 8051 software development including an OTP programmer. IRMCK171 comes in a 48 pin QFP package.1 Overview (5)2 Pinout (6)3 IRMCK171 Block Diagram and Main Functions (7)connection and Pin function (9)4 ApplicationInterface Group (10)Peripheral4.1 8051Peripheral Interface Group (11)4.2 MotionInterface Group (11)4.3 AnalogInterface Group (11)4.4 Power4.5 TestInterface Group (11)5 DCCharacteristics (12)Maximum Ratings (12)5.1 Absolute5.2 System Clock Frequency and Power Consumption (12)5.3 Digital I/O DC Characteristics (13)5.4 PLL and Oscillator DC characteristics (14)5.5 Analog I/O (IFB+,IFB-,IFBO, AIN5+,AIN5-,AIN5O) DC Characteristics (14)5.6 Under Voltage Lockout DC characteristics (15)DC characteristics (15)comparator5.7 Itrip5.8 CMEXT and AREF Characteristics (15)Characteristics (16)6 AC6.1 Digital PLL AC Characteristics (16)6.2 Analog to Digital Converter AC Characteristics (17)6.3 Op amp AC Characteristics (18)6.4 SYNC to SVPWM and A/D Conversion AC Timing (19)6.5 GATEKILLSVPWM AC Timing (20)to6.6 ItripAC Timing (20)6.7 InterruptAC Timing (21)6.8 I2C AC Timing (21)6.9 SPIAC Timing (22)AC Timing (24)6.10 UARTInput AC Timing (25)6.11 CAPTUREProgramming Timing (26)6.12 OTPAC Timing (27)6.13 JTAGStructure (28)7 I/OList (31)8 PinDimensions (33)9 PackageInformation (34)Marking10 PartTable 1 Absolute Maximum Ratings (12)Table 2 System Clock Frequency (12)Table 3 Digital I/O DC Characteristics (13)Table 4 PLL DC Characteristics (14)Table 5 Analog I/O DC Characteristics (14)Table 6 UVcc DC Characteristics (15)Table 7 Itrip DC Characteristics (15)Table 8 CMEXT and AREF DC Characteristics (15)Table 9 PLL AC Characteristics (16)Table 10 A/D Converter AC Characteristics (17)Table 11 Current Sensing OP Amp AC Characteristics (18)Table 12 SYNC AC Characteristics (19)Table 13 GATEKILL to SVPWM AC Timing (20)Table 14 Itrip AC Timing (20)Table 15 Interrupt AC Timing (21)Table 16 I2C AC Timing (21)Table 17 SPI Write AC Timing (22)Table 18 SPI Read AC Timing (23)Table 19 UART AC Timing (24)Table 20 CAPTURE AC Timing (25)Table 21 OTP Programming Timing (26)Table 22 JTAG AC Timing (27)Table 23 Pin List (32)Figure 1 Typical Application Block Diagram Using IRMCK171 (5)Figure 2 Pinout of IRMCK171 (6)Figure 3 Crystal circuit example (16)Figure 4 Voltage droop and S/H hold time (17)Figure 5 A capacitor of 47pF is recommended at the output pin of all op amps (18)Figure 6 SYNC timing (19)Figure 7 Gatekill timing (20)Figure 8 ITRIP timing (20)Figure 9 Interrupt timing (21)Figure 10 I2C Timing (21)Figure 11 SPI write timing (22)Figure 12 SPI read timing (23)Figure 13 UART timing (24)Figure 14 CAPTURE timing (25)Figure 15 OTP programming timing (26)Figure 16 JTAG timing (27)Figure 17 PWMUL/PWMUH/PWMVL/PWMVH/PWMWL/PWMWH output (28)Figure 18 All digital I/O except motor PWM output (28)Figure 19 RESET, GATEKILL I/O (29)Figure 20 Analog input (29)Figure 21 Analog operational amplifier output and AREF I/O structure (29)Figure 22 VPP programming pin I/O structure (30)Figure 23 VSS and AVSS pin structure (30)Figure 24 VDD1 and VDDCAP pin structure (30)Figure 25 XTAL0/XTAL1 pins structure (30)1 OverviewIRMCK171 is a new generation International Rectifier integrated circuit device primarily designed as a one-chip solution for complete inverter controlled appliance motor control applications. Unlike a traditional microcontroller or DSP, the IRMCK171 provides a built-in closed loop sensorless control algorithm using the unique flexible Motion Control Engine (MCE TM) for permanent magnet motors as well as induction motors. The MCE TM consists of a collection of control elements, motion peripherals, a dedicated motion control sequencer and dual port RAM to map internal signal nodes. IRMCK171 also employs a unique single shunt current reconstruction circuit in addition to two leg shunt current sensing circuit to eliminate additional analog/digital circuitry and enables a direct shunt resistor interface to the IC. Motion control programming is achieved using a dedicated graphical compiler integrated into the MATLAB/Simulink TM development environment. Sequencing, user interface, host communication, and upper layer control tasks can be implemented in the 8051 high-speed 8-bit microcontroller. The 8051 microcontroller is equipped with a JTAG port to facilitate emulation and debugging tools. Figure 1 shows a typical application schematic using the IRMCK171.IRMCK171 contains 32K bytes of OTP program ROM, The IRMCF171 contains 64K bytes of Flash RAM and intended for development purposes only while the IRMCK171 is intended for volume production. Both the development and ROM versions come in a 48-pin QFP package with identical pin configuration tofacilitate PC board layout and transition to mass production.Figure 1 Typical Application Block

介绍几种机器人驱动芯片(注：本文已经投稿至《电子制作》)在自制机器人的时候，选择一个合适的驱动电路也是非常重要的。
最初，通常选用的驱动电路是由晶体管控制继电器来改变电机的转向和进退，这种方法目前仍然适用于大功率电机的驱动，但是对于中小功率的电机则极不经济，因为每个继电器要消耗20~100mA的电力。
当然，我们也可以使用组合三极管的方法，但是这种方法制作起来比较麻烦，电路比较复杂，因此，我在此向大家推荐的是采用集成电路的驱动方法：马达专用控制芯片LG9110芯片特点：低静态工作电流；宽电源电压范围：2.5V-12V ；每通道具有800mA 连续电流输出能力；较低的饱和压降；TTL/CMOS 输出电平兼容，可直接连CPU ；输出内置钳位二极管，适用于感性负载；控制和驱动集成于单片IC 之中；具备管脚高压保护功能；工作温度：0 ℃-80 ℃。
描述：LG9110 是为控制和驱动电机设计的两通道推挽式功率放大专用集成电路器件，将分立电路集成在单片IC 之中，使外围器件成本降低，整机可靠性提高。
该芯片有两个TTL/CMOS 兼容电平的输入，具有良好的抗干扰性；两个输出端能直接驱动电机的正反向运动，它具有较大的电流驱动能力，每通道能通过750 ～800mA 的持续电流，峰值电流能力可达1.5 ～2.0A ；同时它具有较低的输出饱和压降；内置的钳位二极管能释放感性负载的反向冲击电流，使它在驱动继电器、直流电机、步进电机或开关功率管的使用上安全可靠。
LG9110 被广泛应用于玩具汽车电机驱动、步进电机驱动和开关功率管等电路上。

Host communications are provided over SPI, RS-232C or Host parallelports. Two current sensing ICs (IR2175 and a three phase high voltage gate drive typically implement the high voltage / current interface between the IRMCK201 IC and motor.The IRMCK201 can operate in a ìst and-al oneîmode without the host controller. A serial EEPROM could beutilized to load motor-specific parameters into the IC.AC PowerFigure 1. Basic Block Diagram of IRMCK201IRMCK201Detailed Block DiagramFigure 2 shows a detailed block diagram or the IRMCK201. All logic and algorithms are pre-programmed, and the user does not need to make any effort to develop code, alleviating the tedious design process. If needed, the user can configure the drive to tailor the control per specific needs to meet the required specification. This configuration is easily done by accessing the host register set through the communication interface.Figure 2.

Typical Connection of IRMCK201IRMCK201IC Crystal Clock CircuitryThe clock input to the IC is a 33.33 MHz crystal oscillator. Two shunt capacitors and possibly a series resistor is required to terminate the crystal to the IC.The values of the R/C will vary based on actual PCB attributes, and some empirical analysis may be required to get the PLL to start oscillating. Once oscillating, verify that the signal waveforms at the OSC1CLK and OSC2CLK pins are sinusoidal rather than trapezoidal. Refer to Table 1 for suggested R/C values. Most low-cost crystals can be used in this application. An example is a Citizen Part number CM309B33.333MABJT available from Digi-Key under part number 300-4160-1-ND.Figure 5. Oscillator CircuitTable 1: Typical Values for the Clock CircuitPLL Clock CircuitryIRMCK201The IRMCK201 contains a PLL that creates a 2X and 4X clock from the input 33.33 MHz input clock pin. There are a number of pins on the IC allocated for factory testing purposes, which need to be left unconnected. Table 2 shows required PCB signal connections for these pins. Note that N/C is for factory use only.Low Pass FilterThe low pass filter for this PLL resides between the CHGO and LPVSS pins. Three passive components arerequired to implement this filter: Cp, Rp and Cs. Figure 6 shows how to place these components around the IC. A shield should be placed below Rp, Cp and Cs made out of copper etch.Shielded by LPVSSIRMCK201I m p l e m e n t i n g t h e L o w P a s s F i l t e r S h i e l dMake all connections between CHGO, Rp, Cp, Cs and LPVSS as short as possible. Create the underlining shield by ìcopper fillingî a larger area in the signal plane of the PCB. Connect this shield to the LPVSS pin of the IC. Do not connect this shield to signal ground (VSS.C p R p a n d C s C o m p o n e n t V a l u e sFor a typical FR4 PCB, the values of the passive components are shown in Table 3.PLL ResetTable 3: PLL Low Pass Filter ValuesThere are two reset pins on the IC, XPD and RESETN both low true. XPD holds the PLL circuitry in reset when low. Upon XPD going high, the PLL circuitry begins to lock onto the 33.33 MHz clock input. The PLL circuit may take up to 1 ms to become stable. RESETN asserted low holds the internal DSP logic in reset. Upon RESETN going high, the IC digital logic becomes active.RESETN should be held low during and at least 1 ms after XPD goes high false to hold the internal DSP logic in reset while the PLL becomes stable.IRMCK201DC Electrical Characteristics and Operating ConditionsAbsolute Maximum RatingsNote: VSS = 0 VoltPARAMETER SYMBOL LIMITSUNIT S NOTEPower SupplyVoltage VDDVSS-0.3 to 4.0 VVSS-0.3 to VDD+0.5V Non 5 VoltInput Voltage VITolerant Pins VSS-0.3 to 7V Only on 5 Volt Tolerant PinsOutput Voltage VO VSS-0.3 to VDD+0.5 V Output Currentper Pin IOUT +/- 30 mATemperatureTstg-65 to 150°CTable 4: Absolute Maximum RatingsRecommended Operating ConditionsNote: VSS = 0 Volt PARAMETER SYMBOL MIN TYP MAX UNITS NOTE Power SupplyVoltage VDD 3.0 3.3 3.6 V VDD V Non 5 Volt Tolerant Pins Input Voltage VI VSS - 5.5 V Pins Ambient TemperatureTa-40-85°CNote 1Table 5: Recommended Operating ConditionsNotes:1.

IRMCK311 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCK311 contains two computation engines. One is Motion Control Engine (MCE TM) for sensorless control of permanent magnet motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The MCE TM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user can program a motion control algorithm by connecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique analog/digital circuit and algorithm to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle instruction execution (16MIPS at 33MHz). The MCE and 8051 microcontroller are connected via dual port RAM to process signal monitoring and command input. An advanced graphic compiler for the MCE TM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCK311 comes with a small QFP64 pin lead-free package.TABLE OF CONTENTS1 Overview (5)2 IRMCK311 Block Diagram and Main Functions (6)3 Pinout (8)4 Input/Output of IRMCK311 (9)4.1 8051 Peripheral Interface Group (10)4.2 Motion Peripheral Interface Group (10)4.3 Analog Interface Group (11)4.4 Power Interface Group (11)4.5 Test Interface (12)5 Application Connections (13)6 DC Characteristics (14)6.1 Absolute Maximum Ratings (14)6.2 System Clock Frequency and Power Consumption (14)6.3 Digital I/O DC Characteristics (15)6.4 PLL and Oscillator DC Characteristics (15)6.5 Analog I/O DC Characteristics (16)6.6 Under Voltage Lockout DC Characteristics (17)6.7 AREF Characteristics (17)7 AC Characteristics (18)7.1 PLL AC Characteristics (18)7.2 Analog to Digital Converter AC Characteristics (19)7.3 Op Amp AC Characteristics (19)7.4 SYNC to SVPWM and A/D Conversion AC Timing (20)7.5 GATEKILL to SVPWM AC Timing (21)7.6 Interrupt AC Timing (21)7.7 I2C AC Timing (22)7.8 SPI AC Timing (23)7.8.1 SPI Write AC timing (23)7.8.2 SPI Read AC Timing (24)7.9 UART AC Timing (25)7.10 CAPTURE Input AC Timing (26)7.11 JTAG AC Timing (27)7.12 OTP Programming Timing (28)8 I/O Structure (29)9 Pin List (32)Dimensions (35)10 Package11 Part Marking Information (36)Information (36)12 OrderingTABLE OF FIGURESFigure 1.

Pin List (32)1 OverviewIRMCK311 is a new International Rectifier integrated circuit device primarily designed as a one-chip solution for complete inverter controlled appliance dual motor control applications. Unlike a traditional microcontroller or DSP, the IRMCK311 provides a built-in closed loop sensorless control algorithm using the unique Motion Control Engine (MCE TM) for permanent magnet motors. The MCE TM consists of a collection of control elements, motion peripherals, a dedicated motion control sequencer and dual port RAM to map internal signal nodes. IRMCK311 also employs a unique single shunt current reconstruction circuit to eliminate additional analog/digital circuitry and enables a direct shunt resistor interface to the IC. The sensorless control is the same for both motors with a single shunt current sensing capability. Motion control programming is achieved using a dedicated graphical compiler integrated into the MATLAB/Simulink TM development environment. Sequencing, user interface, host communication, and upper layer control tasks can be implemented in the 8051 high-speed 8-bit microcontroller. The 8051 microcontroller is equipped with a JTAG port to facilitate emulation and debugging tools. Figure 1 shows a typical application schematic using IRMCK311.IRMCK311 is intended for volume production purpose and contains 64K bytes of OTP (One Time Programming) ROM, which can be programmed through a JTAG port. For a development purpose use, IRMCF311 contains a 48k byte of RAM in place of program OTP to facilitate an application development work. Both IRMCF311 and IRMCK311 come in the same 64-pin QFP package with identical pin configuration to facilitate PC board layout and transition to mass productionFigure 1.

IRMCK201芯片资料1 概述国际整流器件公司(IR)针对高性能交流伺服驱动的需求熒杓瞥隽嘶于FPGA技术的完整的伺服驱动控制解决方案IRMCK201芯片.与传统的运动控制专用DSP芯片不同的是,IRMCK201不仅包含运动控制的外围功能如PWM、编码计数电路、电流传感接口等,而且也包含通过硬件实现的FOC算法和速度控制算法,从而省略了编程任务熂蚧了高性能交流伺服系统的设计,此外它还适用于不同类型的永磁电机或感应电机,因而有很好的应用前景.IRMCK201采用标准的100管脚封装形式,其主要电气特点如下:●完整的电流闭环控制和速度闭环控制;●使用PWM载波频率可以配置速度和电流更新率;●可以配置感应电机或者永磁电机的控制系统;●带死区的空间矢量PWM;●最大时钟输入33.3MHz,最大PWM载波频率83.3kHz,电流环带宽5.5kHz,速度环更新率5/10kHz;●具有与高压线性电流传感器IR2175、高压驱动芯片IR213x、霍尔A/B/C信号、光电编码器、RS232或RS422、快速SPI的接口;●配置光电码盘的线数范围从200PPR～10000PPR;●可以监视直流母线电压;●可以配置模拟参考输入;●2MHz的计数器改善低速性能;●具有4路采样/保持的A/D转换接口;●通过主机寄存器接口,A T24C01A可对内部数据/参数进行初始化;●智能IGBT保护封锁控制;●可以配套使用ServoDesigner配置工具软件.2 IRMCK201内部功能结构图1为IRMCK201内部详细控制结构图.从图中可以看出,作为运动控制芯片,IRMCK201在硬件上具备了伺服控制所必需的控制单元,如带死区时间设置的空间矢量PWM、PARK变换和Clark变换、电流环PI调节器、速度环PI调节器、速度测量单元等,这样用户就省去了编写代码的任务,简化了复杂的设计过程.IRMCK201通过硬件逻辑实现伺服控制功能,芯片的接口可以灵活配置,因而为了实现不同的控制算法,可以通过接口对IRMCK201进行参数设置.以矢量控制的感应电机为例,在内部控制结构中有一个前馈滑模增益路径,可以通过设置相关寄存器来实现这种控制功能.也就是说,上位机仅需将“1”或“0”写入相关寄存器中,就可使该控制功能IRM-CK201也支持其它结构,如除IR2175外的电流传感器接口芯片、电流控制中的前馈增益路径使能/禁止、闭环速度控制的使能/禁止以及速度给定值的选择等.也就是说采用IRMCK201配置伺服系统,只需了解它内部的功能模块和寄存器的情况,并通过上位机对它的寄存器进行配置,即可迅速实现各种功能.例如,要为逆变器设置一个开关频率为10kHz的PWM驱动信号,用户不需要编写程序代码来实现这个PWM信号的算法,只需要对相关寄存器赋值即可.IRMCK201主机通信接口包括RS232/RS485/RS422、快速SPI接口和8位并行接口.因此它可以方便与主机或控制器进行通信,修改和读取其主控寄存器来控制输出.IRMCK201也可以独立运行而不需要外部主机参与控制,其运行参数通过外部EEPROM来保存,上电时自动从EEPROM中读取参数.现以具有电流环和速度环的永磁无刷电机控制系统为例,分析系统的结构.通过配置相关寄存器使能速度闭环控制.对于电流环,由电流传感器IR2175采样电机V 相和W相绕组电流,经过IRMCK201内部计算可以得到U相电流,与V相和W相电流一起组成三相电流,通过Park变换与矢量旋转被分解为产生磁通的励磁电流分量和产生转矩的转矩电流分量熣饬礁鲋绷髁烤哂卸懒⒌谋壤积分调节器.对于速度环,由光电编码信号通过IRMCK201内部测速单元得到速度反馈,它与速度给定值相互比较产生速度偏差.这个偏差经过速度PI调节器产生一个对应的转矩电流Iq,当采用Id=0控制时,Id、Iq即是内部电流环的给定值,它们与实际反馈电流比较产生电流偏差煹缌髌差经过电流环PI调节以后产生输出电压Us-q和Us-d熢谛转坐标系d、q .电压Us-q和Us-d被反变换成静止坐标系下的电压分量熑缓缶过空间矢量PWM计算后煾逆变器的功率模块发出合适的开关信号,控制功率模块开关工作.3 IRMCK201输入输出接口如图2所示,IRMCK201输入输出接口主要包括主机通讯接口、PWM门极信号接口、正交编码器接口、主机通讯接口、A/D接口、串行EEPROM接口、锁相环和系统时钟接口、控制输入和状态指示接口、电流传感器IR2175接口.3.1 PWM门极信号接口IRMCK201提供6路SVPWM输出熗ü光耦与三相桥驱动芯片IR2136进行连接来驱动MOSFET或IGBT熞部梢灾苯佑胫悄芄β誓？(IPM)的6个驱动信号接口相连.同时还提供驱动故障反馈接口.3.2 主机通讯接口IRMCK201提供了多种与外部主机通信的方式.主机可以通过RS232/RS422、SPI接口或8 位并行接口来配置和监控系统的运行.RS232/RS422通信方式可以根据通讯距离进行选择.RS232接口通过MAX232进行电平转换,它允许PC直接对其进行寄存器的配置修改及状态读取,通信波特率可以通过外部引脚来设置.SPI接口方式中,芯片处于从方式,通信最高时钟可达8MHz,可以实现与主机高速通信.不同通信方式通常都处于激活状态,可以相互切换煹不能同时运行.3.3 正交编码器接口IRMCK201带有光电编码器接口电路熆梢苑奖愕刈槌梢桓鏊欧控制系统.它可以与多种编码器接口熉龀迨为200～10000 个/ 转熉龀迤德首罡呖纱1MHz.编码器接口具有相互正交的ENA、ENB编码信号及零点标志信号接口,同时还具有三路HALL信号输入接口.系统上电时可以通过HALL传感器及Z脉冲估算编码器初始值.3.4 控制输入及状态指示接口控制输入信号包括启动、停止、转动方向、输出使能、故障复位、主机状态等;状态指示信号包括系统故障指示、同步指示及两个双色指示灯.可以直接通过对输入引脚的操作来控制电机的运行.3.5 电流传感器IR2175接口IR2175线性电流传感器可以将电流信号从伺服电机的高端驱动电路转换到低端驱动电路熞员憧刂频缏方行处理.在伺服电机相绕组回路中串联一个取样电阻,随着电机相电流的变化熑⊙电阻两端产生一个很小的交流电压信号作为IR2175的输入,它的输出是频率为130kHz、占空比随电流大小变化的PWM数字信号,经过电平转换,PWM信号被转换成了以地为参考点的信号.IR2175 的输入电压变化范围为-260mV～+260mV,因此过载电流流过取样电阻时所产生电压应小于或等于260mV.对于信号的处理,可将IR2175通过光耦直接与IRM-CK201进行连接,再在IRMCK201内部进行电流计算.3.6 A/D接口IRMCK201提供了直接与ADS7818 A/D转换器相连的接口,通过多路复用器CD4052可以输入四路模拟信号,分别为转速或转矩大小控制的模拟输入、直流母线电压的采样输入和其它电流传感器如HALL电流传感器送来的两路相电流信号.但是这里采样的相电流信号只能作为过流保护,不能作为电流环的反馈,也就是说ADS7818不可以取代IR2175对相电流进行取样.4 应用本文利用IRMCK201与TI公司的DSP芯片TMS320LF2407设计了应用于数控机床的永磁无刷交流伺服系统.4.1 系统硬件设计结构框图系统的结构框图如图3所示,整个系统由以下几部分组成:(1)控制部分该交流伺服系统控制电路主要由TMS320LF 2407、IRMCK201和少量的外围电路组成.DSP用于完成IRMCK201的初始化和系统位置环控制算法的实现,并完成系统的键盘和显示功能.IRMCK201内部硬件电路完成系统的电流环、速度环控制,最终产生SVPWM驱动信号,以完成对功率模块的开关控制,同时通过A/D接口对母线电压进行监测,以实现过压保护功能.系统采用2000PPR的增量式光电码盘和霍尔传感器测量电机位置和速度信号,采用IR2175电流传感器对相电流采样,由于IRMCK201提供了IR2175接口,所以采样的电流信号可直接送到IRMCK201作为控制部分的电流反馈.为了增加系统的抗干扰性,本系统采用高速光耦将系统的控制部分和功率部分进行隔离.(2)主电路部分本系统的主电路为AC-DC-AC 逆变电路.输入的三相交流电压经整流、滤波后得到直流电压供给逆变器.功率器件采用IR公司的智能功率模块IRAMS16UP60A,它包括三相高压高速驱动集成芯片IR2136和6个IGBT,其输入驱动信号的最高频率可达20kHz.4.2 系统程序设计由于系统的电流环、速度环控制和过流、过压、欠压等保护功能都由IRMCK201内部硬件实现,所以系统软件主要是用DSP实现交流伺服系统位置环的控制和对IRMCK201的通讯,相比之下程序设计比较简单.图4所示为DSP的主程序流程和位置环中断服务子程序.本系统采用了IRMCK201芯片,结合使用TI公司的DSP芯片TMS320LF2407,大大简化了系统的软硬件设计,缩短了系统开发周期,提高了系统的可靠性,从而实现了高性能的交流伺服系统.。
