Recent Applications of Symbolic Computation in Control System Design

Abstract In this paper we describe several recent applications of symbolic computation to control system design based on MACSYMA. These include routines to calculate the transfer function of a control system in block diagram representation and to compute and simplify state space realizations of multivariable control systems. The programs provide a quick way to formulate design problem and automate the calculation in the initial stage of a control system design process. An example on the application of these routines in the setting up of generalized plant state space realization for use in H ∞ /H 2 optimial control is provided
