Abstract

In this paper we propose a fixed-order controller design method with frequency domain specifications via generalized KYP lemma. The specifications are given on sensitivity function, complementary sensitivity function, and gain/phase margin. Both the numerator and the denominator of the controller satisfying these constraints can be obtained simultaneously. A closed-loop stability condition is given as an LMI via KYP lemma.
