Using MATLAB in a graduate electrical engineering optimal control course

Control system design packages like MATLAB, MATRIX/sub x/, Control C, SIMNON, etc. have become essential ingredients of both undergraduate and graduate courses in the systems and controls area. This work describes our experience, at the Great Valley Campus of the Pennsylvania State University and the University of Arkansas, with the use of one of these packages, namely MATLAB with its Control Systems, Robust Control and LMI toolboxes in an optimal control course. In this paper we describe those standard functions of MATLAB and Control Systems Toolbox that are most appropriate for use in an optimal control course. Next, we focus on some special features of MATLAB that can be used to produce interactive simulations, using user interface controls. With the help of interactive simulations, instructors can effectively illustrate the change in system response due to parameter variations. Examples illustrating these features are included. A discussion of how MATLAB helps in reducing the amount of time spent in performing computational homework assignments and the advantages of using graphics user interface control is given. Finally, the general positive student reaction is reported.
