Computer aided control system design: Multiple design objectives

A new approach to control system design has been implemented in the software described here. The set of controllers simultaneously satisfying multiple design specifications can be obtained without performing a traditional optimization procedure. The most notable strength of the method is that the entire set of controllers, satisfying some of the most important specifications such as stability and robust stability can be described first by sets of linear inequalities within which performance is sought. This paper describes the basic principle of the design method along with a series of examples for illustration.
