Controller Reduction of Parameter Dependent Systems

Abstract

This paper proposes a controller reduction of linier parameter dependent systems. A measure of the degradation is derived foer the parameter dependent closed-loop performance caused by applying the reduced-order dependent controller. this measure can be obtained by extending the degradation of the closed-loop performance of the balanced truncation of the corresponding time invariant system. To verify the performance of the reduced-order controller, an application of the proposed controller reduction method to vertical acceleration of a missile is presented
