Design of a Guaranteed Cost Controller for a Class of Systems with Uncertain Parameters

불확정 피라미터를 갖는 시스템에 대한 Guaranteed Cost 제어기의 설계

This paper describes a method to design a guaranteed cost controller for a system with uncertain parameters. The design procedure consists of defining an arbitrary function which satisfies certain condition and minimizing it over the control input. When the method is applied to a class kof linear systems with uncertain parameters, a Riccati equation with additional terms results. A simple example is presented to illustrate the usefulness of this method.
