Abstract

SIMULINK is a tool for modeling, analyzing, and simulating physical and mathematical systems, including those with nonlinear elements and those that make use of continuous and discrete time. As an extension of MATLAB®, SIMULINK adds many features specific to dynamic systems for powerful and intuitive modeling. This paper introduces the basic elements of the SIMULINK in MATLAB® and describes how to use SIMULINK as a teaching tool to determine a target value for a design variable. This technique is applicable for use in teaching a design course or in a numerical methods course. We have solved two popular single degree of freedom dynamic problems to validate the proposed methodology. Several electrical or mechanical engineering courses such as ELEN 390 Linear Systems, ELEN 431 Control Systems Analysis, and MEEN 456 Engineering Modeling, Analysis and Control can be effectively use this technique to build the subject concepts and solve numerical problems in class. The present paper discusses and describes possible ways of using SIMULINK in ELEN 390 Linear Systems course. Possibilities of developing a control system for interactive problem solving are also discussed. Some unique advantages of SIMULINK include visualization of problem, extensive monitoring and evaluation of students’ performance at each problem solving step, instant feedback and fair evaluation. Extensive data gathering on students’ performance leading to better identification of each student’s weak points will help in deciding the future orientation of the course at each step.

Introduction

Simulink1 is a software package for modeling, simulating, and analyzing dynamic systems (whose outputs change over time). It can be used to explore the behavior of a wide range of real-world dynamic systems, including electrical circuits, shock absorbers, braking systems, and many other electrical, mechanical, and thermodynamic systems. It also supports linear and nonlinear systems, modeled in continuous time, sampled time, or a hybrid of the two. Systems can also be multi-rate, i.e., have different parts that are sampled or updated at different rates. For modeling, Simulink provides a graphical user
