Lecture12_Block_Diagram_and_Signal_Flow_Graph
Digital Signal ProcessingLecture12Block Diagram and Signal Flow Graph Representationof LTI SystemsTesheng Hsiao,Associate ProfessorSuppose that the input and output of a causal LTI system satisfy the following linear constant-coefficient equationy[n]−N∑k=1a k y[n−k]=M∑k=0b k x[n−k](1)The input and output relation can be expressed by the convolution sum or the system functiony[n]=∞∑k=0h[k]x[n−k](2)Y(z)=H(z)X(z)(3)whereH(z)=∑Mk=0b k z−k 1−∑Nk=1a k z−kAlthough all these representations are theoretically equivalent,they result in different computational effects when they are implemented by digital computers or circuits.In this lecture,we will introduce several representations of Eq.(1),each of which has its own com-putational characteristics.1Block Diagram Representation of LTI SystemsThree basic operations are required to implement Eq.(1):addition,multiplication(by a constant coefficient),and(one-step)delay.The following example illustrates these operations and pictorial expressions.Example1Consider the systemy[n]=a1y[n−1]+a2y[n−2]+b0x[n]The corresponding system function isH(z)=b01−a1z−a2zThe block diagram of this system is shown in Fig.(1).The addition,multiplication,and delay are represented by different symbols.Figure 1:Block diagram of the system in Example 1Consider the general case,i.e.the system described by Eq.(1).The block diagram is shown in Fig.(2).This realization is called direct form I .In direct form I realization,the output is obtained through two steps:v [n ]=M ∑k =0b k x [n −k ]y [n ]=N ∑k =1a k y [n −k ]+v [n ]or equivalently,V (z )=H ma (z )X (z )={M ∑k =0b k z −k }X (z )Y (z )=H ar (z )V (z )={11−∑N k =1a k z −k }V (z )and H (z )=H ar (z )H ma (z ).Figure 2:Direct Form I representation of an LTI systemSince both H ar(z)and H ma(z)are LIT systems.We can exchange the order and leave the results unaltered.Hence the system can be implemented in a different way:W(z)=H ar(z)X(z)Y(z)=H ma(z)W(z)or equivalently,w[n]=N∑k=1a k w[n−k]+x[n]y[n]=M∑k=0b k w[n−k]This results in the block diagram in Fig.(3).Figure3:Direct Form II representation of an LTI system In Fig.(3),the two columns of delays contains the same values(w[n−k]);hence they can be combined into one column of delays as shown in Fig.(4).The realization in Fig.(4) is called direct form II or canonic direct form.One distinct property of direct form I and II is the number of delays.In other words, the required size of storage space(memory or register)is different.Direct form I contains N+M delays whereas direct form II has max{M,N}delays.Hence direct form II is more efficient in terms of space usage.An implementation with the minimum number of delay elements is commonly referred to as a canonic form implementation.Example2Consider the LTI systemH(z)=1+2z−11−1.5z−1+0.9z−2The direct form I and II implementation are shown in Fig.(5)and Fig.(6)respectively.Figure4:Direct Form II representation of an LTI systemFigure5:Direct form I of Example22Signal Flow Graph Representation of LTI Systems Instead of using block diagrams introduced in the previous section,we usually use signal flow graph to represent a system described by Eq.(1)because signalflow graphs are more compact.A signalflow graph consists of nodes and directed branches.A node denotes a variable or a sequence.A node could have several entering and leaving branches.A branch connects a pair of nodes with an arrow denoting the direction.Each branch represents a linear operation,such as multiplication or delay,on the departure node.The operation carried out by each branch is denoted by that branch.It denotes the unity gain multiplication if there is no notation associated with the branch.The value of a node is the sum of all entering branches.There are two special nodes in the signalflow graph.Source nodes are nodes that have no entering branches.Source nodes are used to represent the injection of external inputs or signal sources into the graph.Sink nodes are nodes that have only entering branches.Sink nodes are used to extract outputs from the graph.Figure6:Direct form II of Example2Fig.(7)illustrates the direct form II and signalflow graph of afirst order IIR system. The equations represented by Fig.(7b)arew1[n]=aw4[n]+x[n]w2[n]=w1[n]w3[n]=b0w2[n]+b1w4[n]w4[n]=w2[n−1]y[n]=w3[n]These equations can be rearranged,eliminating redundant variables,and becomew2[n]=aw2[n−1]+x[n]y[n]=b0w2[n]+b1w2[n−1]which are exactly the equations represented by direct form II.Figure7:(a)Direct form II(b)Signal Flow GraphOn the other hand,given a signalflow graph,we want to derive the system function from it.The z-transform techniques would be useful in this case,as explained by the following example.Example3Given the signalflow graph in Fig.(8).We can write down the equations for each node:w1[n]=w4[n]−x[n]w2[n]=αw1[n]w3[n]=w2[n]+x[n]w4[n]=w3[n−1]y[n]=w2[n]+w4[n]Take z-transform on both sides,we haveW1(z)=W4(z)−X(z)W2(z)=αW1(z)W3(z)=W2(z)+X(z)W4(z)=z−1W3(z)Y(z)=W2(z)+W4(z)Eliminate W1(z)and W3(z),we obtainW2(z)=α(W4(z)−X(z))(4)W4(z)=z−1(W2(z)+X(z))(5)Y(z)=W2(z)+W4(z)Solving Eq.(4)and Eq.(5)simultaneously,we haveW2(z)=α(z−1−1)1−αz−1X(z)W4(z)=z−1(1−α)1−αz−1X(z)Therefore the system function isY(z)=(α(z−1−1)+z−1(1−α)1−αz−1)X(z)=(z−1−α1−αz−1)X(z)Note that the direct form I representation of the system function is shown in Fig.(9).In direct form I representation,2delay elements and two multiplications are required.Direct form II representation needs one delay element but still two multiplications.In the represen-tation of Fig.(8),only one delay element and one multiplication is required.Figure8:Signalflow graph for Example3Figure9:Direct Form I representation of the system function in Example3。

Memory and Speed Optimization F. Using Comments in Block Diagram G. Monitoring VI Performance Using the Profile Window H. Block Diagram ChecklistA. Hierarchical DesignOrganize the VIs in the file system to reflect the hierarchical nature of the software. Create a directory for all the VIs for one application and give it ameaningful name, as shown in Figure 3-1.File pathWhen naming VIs, VI libraries, and directories, avoid using characters that are not accepted by all file systems, such as slash (/), backslash (\), colon (:), tilde (~), and so on. Select Tools» Options to make sure the VI Search Path contains <topvi>\* and <foundvi>\*. Avoid creating files with the same name anywhere within the hierarchy.B. DataflowLabVIEW was designed to use a left-to-right and sometimes top-to-bottom layout. Block diagrams should follow this convention. While the positions of program elements do not determine execution order, avoid wiring from right to left. Only wires and structures determine execution orderDataflowBecause the block diagram in the following figure does not follow left-to-right and top-to-bottom layout, it is very difficult to discern how data flows.DataflowUsing left-to-right and top-to-bottom layout, the same block diagram is much clearer, as shown in the following figure.C. Use Good Wiring TechniquesThe Align and Distribute feature in LabVIEW can make it easy to quickly arrange objects on the block diagram to make it easier to see and understand groupings of objects. Placing objects using symmetry and straight lines can make the block diagram easier to read. Some other good wiring tips are.Some other good wiring tips areAvoid placing any wires under any block diagram objects such as subVIs or structures. Add as few bends in the wires as possible while trying to keep the wires short. Avoid creating wires with long complicated paths that can be confusing. Delete any extraneous wires to keep block diagram clean.Some other good wiring tips areAvoid the use of local variables when it is possible to pass the data by wire. Every local variable that reads the data makes a copy of it. Try not to pass wires though structures if the data in the wire itself is not used within the structure. Evenly space parallel wires in straight lines and around corners.D. Error HandlingLabVIEW does not handle errors automatically. VIs and functions return errors in one of two ways—with numeric error codes or with an error cluster. Error handling in LabVIEW follows the dataflow model. As the VI runs, LabVIEW tests for errors at each execution node.Error ClustersThe error clusters located on the Controls» Array&Cluster palette include the following components of information: • status is a Boolean value that reports TRUE if an error occurred. • code is a signed 32-bit integer that identifies the error numerically. • source is a string that identifies where the error occurred.Using While Loops for Error HandlingYou can wire an error cluster to the conditional terminal of a While Loop to stop the iteration of the While Loop. When an error cluster is wired to the conditional terminal, the shortcut menu items Stop if True and Continue if True change to Stop on Error and Continue while Error.Using Case Structures for Error HandlingWhen you wire an error cluster to the selector terminal of a Case structure, the case selector label displays two cases, Error and No Error, and the border of the Case structure changes color—red for Error and green for No Error. If an error occurs, the Case structure executes the Error subdiagram.E. Memory and Speed OptimizationWaits in Loops If speed is not necessary to a While Loop, add a Wait function to avoid the problem of slowing down other tasks. Typically a delay of 50 to 100 MS is sufficient, but other factors in the application might affect the delay.Waits in LoopsThe delay does not have to have any data dependencies, as shown in Figure 3-2.Efficient Use of ArraysIf possible, do not build arrays using the Build Array function within a loop because the function makes repetitive calls to the memory manager. A more efficient method of building an array is to use auto-indexing or pre-size the array and use the Replace Array Element function to place values in it. Similar issues exist when dealing with strings because in memory, LabVIEW handles strings as arrays of characters.Efficient Use of Local and Global VariablesUse global and local variables as sparingly as possible. You can use both global and local variables to write VIs very efficiently. However, if you misuse or abuse global and local variables, the memory usage of the VI increases and the performance is affected.Avoid Unnecessary Data CoercionChoosing the proper data type for the data to be handled can be important in controlling the memory usage of the application.Avoiding coercion dots also can help you reduce unnecessary memory usage and speed.Avoid Unnecessary Front Panel OverheadConsider indicator overhead when designing the VI if performance is a concern for the application. To optimize the performance of the VI, only display the necessary information on the front panel and only send data to indicators if the data is different from what is already displayed.Sizing and PositioningThe size of the block diagram window can affect how readable your LabVIEW code is to others. While it is good to be aware of the size of the block diagram window, it is also very important to ensure that the LabVIEW code that is displayed in it is not too large. Code that requires the user to scroll only horizontally or vertically is acceptable as long as the user does not have to scroll an unreasonable amount to view the entire code.F. Using Comments in Block DiagramUse comments on the block diagrams to explain what the code is doing. Omit labels on function and subVI calls because they tend to be large and unwieldy. Use free labels on wires to identify their use. This is particularly useful for wires coming from shift registers. Use labels on structures to specify the main functionality of that structure. Use labels on constants to specify the nature of the constant.G. Monitoring VI PerformanceYou can use the Profile window to analyze how your application uses execution time and memory. The Profile window displays the performance information for all VIs in memory in an interactive table format. To show the Profile window, select Tools» Advanced» Profile VIs. You must select the Profile Memory Usage option before starting a profiling session. Many of the options in the Profile window are available only after you begin a profiling session.H. Block Diagram ChecklistUse the following checklist to ensure you use proper block diagram design in your VIs. Avoid creating extremely large block diagrams. Limit the scrolling necessary to see in the entire block diagram to one direction. Label controls, important functions, constants, property nodes, local variables, global variables, and structures. Add comments. Use object labels instead of free labels where applicable and scrollable string constants for long comments.Block Diagram ChecklistPlace labels below objects when possible and rightjustify text if label is placed to the left of an object. Use standard, consistent font conventions throughout. Use Size to Text for all text and add carriage returns if necessary. Reduce white space in smaller block diagrams but allow at least 3 or 4 pixels between objects.Block Diagram ChecklistFlow data from left to right. Wires enter from the left and exit to the right, not the top or the bottom. Align and distribute functions, terminals, and constants. Label long wires with small labels with white backgrounds. Do not wire behind objects. Make good use of reusable, testable subVIs.Block Diagram ChecklistMake sure the program can deal with error conditions and invalid values. Save with the most important or the first frame of structures showing. Review for efficiency, especially data copying, and accuracy, especially parts without data dependency.。

Profibus配置提示(第1版)说明书
ObjectiveProvide tips for configuring different Profibus PLC tools used with SSD Drives products EquipmentMaster PLC, Profibus Techbox (6053/6055) or Profibus LinkCard (L5353)ProcedureA LL PLC CONFIGURING TOOLS:Delete all internal software input connections to the drive parameter that the PLC writes to.Otherwise, the internal connection will overwrite the Profibus data to the specified tag number.Any drive parameter with a TAG number can be written to or read from. However, all I/O points that attach to customer connections must be processed properly (triggered). Any function block output under the SYSTEM::CONFIGURE I/O::BLOCK DIAGRAM that is being read by the PLC must be triggered. The examples below show how to trigger correctly.Note: The value for Analog Input 1 is read directly at Setpoint Sum 1::Input 0. The Setpoint Sum 1 block is the trigger for Analog Input 1.Note: The value for Analog Input 2 is read directly at the miniLINK. The miniLINK block is the trigger for Analog Input 2.If you have questions, please call the Product Support Group at (704) 588-3246.The SSD Drives gsd file forces all parameters to be transferred and received as 16-bits.Please visit Resource Center for Profibus manuals and other gsd files.Note: Remember that different configuration tools work differently. Some tools use an import command to install new gsd files. Some copy the gsd to a directory, then either restartthe tool or use a scan gsd command. Other tools just copy the gsd to a directory.Note: The euro3245.gsd requires the first 3 bytes of the User_Param_Data to be set to zeroes.Refer to pages 10 and 11 of HA467329U001 Issue 1.U SING A S IEMENS S7PLC TO CONFIGURE A L5353The following Organization Blocks, OB82, OB85, OB06, and OB122 are “highly” recommended to complete the setup for the PLC. These Organization Blocks keep the PLC from stopping communications and/or simulating a fatal error to the module.Also, uncheck the “Turn on Cyclic Distribution of the Bus Parameters” in the DP monitoring setup. When the PLC has power applied, a Global reset command is initiated and can sometimes simulate a communications error.U SING A GE90_30 PLC WITH V ERSA P RO TO CONFIGURE A 6055/PROF/00The GE Profibus configuration software (Versa Pro) does not support user parameter data larger than 25 bytes in length. The SSD Drives GSD file specifies 63 bytes of user parameter data for the 590+. Users must alter the SSD Drives GSD before importing to the GE hardware configuration software. The end result is that the amount of data that can exchanged between the master and drive is limited to 11 words. GE PLC's do not ground the face of the ProfiBus interface cards or remote I/O, Siemens does.Note: An example connection is on the following pageIf you have questions, please call the Product Support Group at (704) 588-3246.If you have questions, please call the Product Support Group at (704) 588-3246.If you have questions, please call the Product Support Group at (704) 588-3246.ObjectiveTo setup communications between a Siemens PLC S7-315 Master to SSD Drives Profibus communication module L5353.EquipmentS7 PLC, Simatic Manager Step 7 Software, L5300 or L5392, L5311, and L5353.

block_diag函数
block_diag函数block_diag函数是Python中的一个函数,用于构造一个块对角矩阵。
该函数在科学计算、矩阵计算以及信号处理等方面广泛应用。
```numpy.block_diag(*arrs)````*arrs`表示要构造的矩阵块的元组序列,这些矩阵块必须是二维数组。
例如:```pythonimport numpy as npa = np.array([[1, 2], [3, 4]])b = np.array([[5, 6], [7, 8]])c = np.array([[9, 10], [11, 12]])d = np.block([[a, np.zeros((2, 2))], [np.zeros((2, 2)), b], [np.zeros((2,4))]])e = np.block([c, np.identity(2)])print(d)print(e)```输出结果如下:```[[1. 2. 0. 0.][3. 4. 0. 0.][0. 0. 5. 6.][0. 0. 7. 8.][0. 0. 0. 0.][0. 0. 0. 0.]][[ 9. 10. 1. 0.][11. 12. 0. 1.]]```在上述例子中,首先定义了三个矩阵块a、b和c,然后使用`np.block`函数将它们拼接成新的二维数组。
具体来说,`d`是由矩阵块a、b和一个2x4的零矩阵构成,拼接在一起形成的,而`e`则是由矩阵块c和一个2x2的单位矩阵构成。
除了`block_diag`函数外,numpy还提供了一些其他的构造函数,例如`numpy.concatenate`、`numpy.vstack`、`numpy.hstack`等。
这些函数也可以用于构造矩阵块。
不过需要注意的是,这些函数构造的矩阵块必须维度相同,而`block_diag`函数则可以将不同形状的矩阵块拼接在一起,同时在拼接部位填充零矩阵。
