If installed, the Simulink Library Browser will soon pop up.
Click on the new icon, identical to a MS Word new file icon. That is your space to work in. After creating a model it can be saved using the save icon. To build simulation models, you will be creating block diagrams just like we draw by hand. In general all blocks are double-clickable to change the values within. In general you can connect the ports on each block via arrows easily via clicking and dragging with the mouse. You can also double-click any arrow these are the controls variables to label what it is. Same with all block labels simulink will give a default name that you can change.
Sources are inputs and sinks are outputs. If you click around in the Simulink Library Browser, you will see the possible sources, blocks, and sinks you have at your disposal. Now let us create a simple one-block transfer function and simulate it subject to a unit step input. Click the new icon in the Simulink Library Browser to get a window to work in untitled with the simulink logo.
Double-click the Continuous button in the Simulink Library Browser to see what blocks are provided for continuous control systems. Grab and slide the Transfer Fcn block to your workspace. Double-click the block in your workspace and enter  in Numerator coefficients and [1 2 8] in Denominator coefficients and close by clicking OK.
Simulink will update the transfer function in the block, both mathematically and visually. Go ahead and save your model on your flash drive as name. Click the Sources tab in the Simulink Library Browser to see what source blocks are provided. You will find a Step, Ramp, Since Wave, etc. Grab and slide the Step block to your workspace.
Double-click the Step block in your workspace and ensure 1 is already entered as the final value for a unit step and that 0 is the Initial value.danardono.com.or.id/libraries/map2.php

Close by clicking OK. Draw an arrow from the Step block to the Transfer Fcn block by using the mouse. Click and drag to the input port of the Transfer Fcn block; when you see a double-plus, let go and the arrow will be connected. Click the Sinks tab in the Simulink Library Browser to see what sink blocks are provided.
Grab and slide the Scope block to your workspace. Draw an arrow from the Transfer Fcn block to the Scope block by using the mouse, the same method as before. To run the model solve the associated differential equation numerically and plot the output results vs.

After it runs, double-click on your Scope to display the results. Click the binoculars icon to zoom in automatically. When I perform these steps, there are two immediate problems: i. These are easy to fix: i. Double-click the Step block and change the Start time to 0 from the default 1 sec, then click OK. Look for Refine output in the window and change the Refine factor from 1 to 10, then click OK.
Re-run and ensure the plot is now acceptably smooth. Finally in this open-loop simulation example, it appears that 10 sec final time is a bit too much. Near the play button in your workspace is an unidentified number This is the default final time. Change it to 8. If you reduce final time less than 8. Your final model will look like this be sure to be a control freak like Dr.

Bob and line up all the arrows and blocks in a rectangular grid. I also renamed the blocks and labeled the variables. Simulink is fast, easy, and fun! Another group of simulink blocks you may use a lot is under Math Operations in the Simulink Library Browser. In particular, we use the Sum summing junction and Gain multiplication by a constant a lot in controls. In addition I find the Mux multiplexer and Demux demultiplexer very useful, especially the Mux to combine two or more variables for plotting on a common scope. Plot both open- and closed-loop unit step responses and compare and discuss.
Hint: put a summing junction between the Step input and the OL system transfer function. Double-click the sum to make the correct signs i. Then pull an arrow down from the negative summing port, turn the corner without letting go.

Then you will have to let go, but click immediately without moving the mouse and hover it over the output y line. When you get the double-plus, let go and you have just made a pickoff point, for the output y feedback. Be sure to use proper m-file filenames.
There can be no leading number, i. There can be no spaces in your filename, i. You can use the underbar instead of spaces and you can use numerical characters as long as they are not the leading character.

Undefined function or variable 'WHOS'. However, if you want to run an m-file name. There are two potential fixes for this error. The same information could have been determined from length x , length y or size x , size y. A common plotting error with newbies is when the user wants to plot an entire array vs. By mistake, the user only plots a single scalar.

Subscript indices must either be real positive integers or logicals. Index exceeds matrix dimensions. The fix for this error is to drop the i notation on the left-hand side. In general, if you are within a loop, only use the i notation on the left-hand side when you want to save that particular variable for later plotting or other operations.
If the variable is intermediate and you dont care about it, drop the i notation and then it will be overwritten the next time through the loop. If you intended to make an animation of robot or mechanism motion in a for loop of N steps but instead got N separate plot windows, you must move the figure; statement to outside the for loop.
Then use close all; to kill the unwanted N figures on your screen prior to trying the program again. Undefined variable "name" or class "name. Sample m-files The following example m-files are given on the following pages.
