Experiment 1Introduction to Simulink1.1 ObjectiveThe objective of Experiment #1 is to familiarize the students with simulation of power electronic circuits in Matlab/Simulink environment. Please follow the instructions in the laboratory manual.1.2 Simulink Basics TutorialSimulink is a graphical extension to MATLAB for the modeling and simulation of systems. In Simulink, systems are drawn on screen as block diagrams. Many elements of block diagrams are available (such as transfer functions, summing junctions, etc.), as well as virtual input devices (such as function generators) and output devices (such as oscilloscopes). Simulink is integrated with MATLAB and data can be easily transferred between the programs. In this tutorial, we will introduce the basics of using Simulink to model and simulate a system.1.2.1 Starting SimulinkSimulink is started from the MATLAB command prompt by entering the following command: >>simulinkAlternatively, you can click on the "Simulink Library Browser" button at the top of the M ATLAB command window as shown below:The Simulink Library Browser window should now appear on the screen. Most of the blocks needed for modeling basic systems can be found in the subfolders of the main "Simulink" folder (opened by clicking on the "+" in front of "Simulink"). Once the "Simulink" folder has been opened, the Library Browser window should look like:1.2.2 Basic ElementsThere are two major classes of elements in Simulink: blocks and lines. Blocks are used to generate, modify, combine, output, and display signals. Lines are used to transfer signals from one block to another. BlocksThe subfolders underneath the "Simulink" folder indicate the general classes of blocks available for us to use:•Continuous: Linear, continuous-time system elements (integrators, transfer functions, state-space models, etc.)•Discrete: Linear, discrete-time system elements (integrators, transfer functions, state-space models, etc.)•Functions & Tables: User-defined functions and tables for interpolating function values•Math: Mathematical operators (sum, gain, dot product, etc.)•Nonlinear: Nonlinear operators (coulomb/viscous friction, switches, relays, etc.)•Signals & Systems: Blocks for controlling/monitoring signal(s) and for creating subsystems•Sinks: Used to output or display signals (displays, scopes, graphs, etc.)•Sources: Used to generate various signals (step, ramp, sinusoidal, etc.)Blocks have zero to several input terminals and zero to several output terminals. Unused input terminals are indicated by a small open triangle. Unused output terminals are indicated by a small triangular point. The block shown below has an unused input terminal on the left and an unused output terminal on the right.LinesLines transmit signals in the direction indicated by the arrow. Lines must always transmit signals from the output terminal of one block to the input terminal of another block. One exception to this is that a line can tap off of another line. This sends the original signal to each of two (or more) destination blocks, as shown below:Lines can never inject a signal into another line; lines must be combined through the use of a block such as a summing junction.A signal can be either a scalar signal or a vector signal. For Single-Input, Single-Output systems, scalar signals are generally used. For Multi-Input, Multi-Output systems, vector signals are often used, consisting of two or more scalar signals. The lines used to transmit scalar and vector signals are identical. The type of signal carried by a line is determined by the blocks on either end of the line.1.2.3 Building a SystemTo demonstrate how a system is represented using Simulink, we will build the block diagram for a simple model consisting of a sinusoidal input multiplied by a constant gain, which is shown below:This model will consist of three blocks: Sine Wave, Gain, and Scope. The Sine Wave is a Source Block from which a sinusoidal input signal originates. This signal is transferred through a line in the direction indicated by the arrow to the Gain Math Block. The Gain block modifies its input signal (multiplies it by a constant value) and outputs a new signal through a line to the Scope block. The Scope is a Sink Block used to display a signal (much like an oscilloscope).We begin building our system by bringing up a new model window in which to create the block diagram. This is done by clicking on the "New Model" button in the toolbar of the Simulink Library Browser (looks like a blank page).Building the system model is then accomplished through a series of steps:1.The necessary blocks are gathered from the Library Browser and placed in the model window.2.The parameters of the blocks are then modified to correspond with the system we are modeling.3.Finally, the blocks are connected with lines to complete the model.Each of these steps will be explained in detail using our example system. Once a system is built, simulations are run to analyze its behavior.Gathering BlocksEach of the blocks we will use in our example model will be taken from the Simulink Library Browser. To place the Sine Wave block into the model window, follow these steps:1.Click on the "+" in front of "Sources" (this is a subfolder beneath the "Simulink" folder) todisplay the various source blocks available for us to use.2.Scroll down until you see the "Sine Wave" block. Clicking on this will display a shortexplanation of what that block does in the space below the folder list:3. To insert a Sine Wave block into your model window, click on it in the Library Browser and drag the block into your workspace.The same method can be used to place the Gain and Scope blocks in the model window. The "Gain" block can be found in the "Math" subfolder and the "Scope" block is located in the "Sink" subfolder. Arrange the three blocks in the workspace (done by selecting and dragging an individual block to a new location) so that they look similar to the following:Modifying the BlocksSimulink allows us to modify the blocks in our model so that they accurately reflect the characteristics of the system we are analyzing. For example, we can modify the Sine Wave block by double-clicking on it. Doing so will cause the following window to appear:This window allows us to adjust the amplitude, frequency, and phase shift of the sinusoidal input. The "Sample time" value indicates the time interval between successive readings of the signal. Setting this value to 0 indicates the signal is sampled continuously.Let us assume that our system's sinusoidal input has:•Amplitude = 2•Frequency = pi•Phase = pi/2Enter these values into the appropriate fields (leave the "Sample time" set to 0) and click "OK" to accept them and exit the window. Note that the frequency and phase for our system contain 'pi' (3.1415...). These values can be entered into Simulink just as they have been shown.Next, we modify the Gain block by double-clicking on it in the model window. The following window will then appear:Note that Simulink gives a brief explanation of the block's function in the top portion of this window. In the case of the Gain block, the signal input to the block (u) is multiplied by a constant (k) to create the block's output signal (y). Changing the "Gain" parameter in this window changes the value of k.For our system, set k = 5. Enter this value in the "Gain" field, and click "OK" to close the window.The Scope block simply plots its input signal as a function of time, and thus there are no system parameters that we can change for it. We will look at the Scope block in more detail after we have run our simulation.Connecting the BlocksFor a block diagram to accurately reflect the system we are modeling, the Simulink blocks must be properly connected. In our example system, the signal output by the Sine Wave block is transmitted to the Gain block. The Gain block amplifies this signal and outputs its new value to the Scope block, which graphs the signal as a function of time. Thus, we need to draw lines from the output of the Sine Wave block to the input of the Gain block, and from the output of the Gain block to the input of the Scope block.Lines are drawn by dragging the mouse from where a signal starts (output terminal of a block) to where it ends (input terminal of another block). When drawing lines, it is important to make sure that the signal reaches each of its intended terminals. Simulink will turn the mouse pointer into a crosshair when it is close enough to an output terminal to begin drawing a line, and the pointer will change into a double crosshair when it is close enough to snap to an input terminal. A signal is properly connected if its arrowhead is filled in. If the arrowhead is open, it means the signal is not connected to both blocks. To fix an open signal, you can treat the open arrowhead as an output terminal and continue drawing the line to an input terminal in the same manner as explained before.Properly Connected SignalWhen drawing lines, you do not need to worry about the path you follow. The lines will route themselves automatically. Once blocks are connected, they can be repositioned for a neater appearance. This is done by clicking on and dragging each block to its desired location (signals will stay properly connected and will re-route themselves).After drawing in the lines and repositioning the blocks, the example system model should look like:In some models, it will be necessary to branch a signal so that it is transmitted to two or more different input terminals. This is done by first placing the mouse cursor at the location where the signal is to branch. Then, using either the CTRL key in conjunction with the left mouse button or just the right mouse button, drag the new line to its intended destination. This method was used to construct the branch in the Sine Wave output signal shown below:The routing of lines and the location of branches can be changed by dragging them to their desired new position. To delete an incorrectly drawn line, simply click on it to select it, and hit the DELETE key.1.2.4. Running SimulationsNow that our model has been constructed, we are ready to simulate the system. Before starting simulation, we need to set the simulation parameters. To do this, go to the Simulation menu and click on Configuration Parameters. The Configuration Parameters dialog box opens on your desktopEnter desired stop time (e.g. 100 microseconds), and change the Solver Options from Variable-step to fix-step and the step size to 1e-4. The step size specifies the resolution of simulation. Click Apply and OK to close the Configuration Parameters window.Go to the Simulation menu and click on Start, or just click on the "Start/Pause Simulation" button in the model window toolbar (looks like the "Play" button on a VCR). Because our example is a relatively simple model, its simulation runs almost instantaneously. With more complicated systems, however, you will be able to see the progress of the simulation by observing its running time in the lower box of the model window. Double-click the Scope block to view the output of the Gain block for the simulation as a function of time. Once the Scope window appears, click the "Auto scale" button in its toolbar (looks like a pair of binoculars) to scale the graph to better fit the window. Having done this, you should see the following:。
