Department of Chemical Engineering University of Texas, Austin ChE 360 Spring 2002 Introduction to the MATLAB SIMULINK Program Adapted from similar document by Dept. of Chemical Engineering, UC - Santa Barbara MATLAB, which stands for MATrix LABoratory , is a technical computing environment for high-performance numeric computation and visualization. SIMULINK is a part of MATLAB that can be used to simulate dynamic systems. To facilitate model definition, SIMULINK adds a new class of windows called block diagram windows. In these windows, models are created and edited primarily by mouse-driven commands. Part of mastering SIMULINK is to become familiar with manipulating model components within these windows. The purpose of this tutorial is to introduce you to SIMULINK and give you experience simulating dynamic systems. In the first part of this tutorial, you will use SIMULINK to generate an open-loop set-point and load response for the process shown in Example 12.7. In the second part of the tutorial, you will generate the closed-loop set-point and load responses shown in Example 12.7 of your textbook (SEM). Please review Example 12.7 on page 288 before attempting this tutorial. Log onto one of the PC computers. Click on the Microsoft “Start” button in the bottom corner of your screen and MATLAB will be listed under “Programs”. Open MATLAB. To invoke SIMULINK, type simulink at the MATLAB prompt which is indicated by “>>” in Figure 1 below. A new window titled simulink will open somewhere on the screen. Figure1. Initial Matlab Screen 1

Figure 2. Simulink Library Browser You will have to right click on the Simulink block to make the menu on the right viewable. Once the simulink window block on the right is open, you are ready to build a SIMULINK model. This tutorial is divided into two sections. In the first section, you will build a model of the open-loop system for the process in Example 12.7 and determine the unit set-point and unit load responses. In the second section, you will build a closed-loop model of the same process. After the closed-loop model is constructed, you should simulate the unit load response and the unit set-point response for two different PID controller tuning methods, ITAE (set-point) and ITAE (load), in Table 12.5. The following steps will guide you through the discussed tasks. Construction of an Open-Loop Block Diagram (Chapters 4, 5, 6, and 7) 1. Open a new empty system window by selecting New followed by Model from the File menu in the simulink window. The new window will be titled untitled . You will build your closed loop model inside this window. Save the empty model by choosing Save from the File menu in the untitled window. Name the model, examplesim. From this point on, the model will be referred to as examplesim . 2.
