Abstract
Computer Aided Design (CAD) systems are essential tool in applying the control theories to the practical problem. Recently various CAD systems of control ssystems have been developed. However all these systems are based on numerical calculation, Hence they are not available for the problem in which the parameters of mathematical models are given as symbols.
This study developed a CAD system which can handle symbolic parameters by using symbolic and algeblaic manipulation system REDUCE 3.1. It is shown that this CAD system can treat the wider problems than the conventional one, for example, the investgation of generic property of the system and designing a controller by exact model matching technique.
