  • Abstract
    In this paper we investigate the design of reduced order controllers using an H∞ framework. Provided there exists a stabilising controller, K0, giving satisfactory closed loop performance we derive frequency weights such that if ||W 2-1(K-K0)W1-1 ||∞<1 then K is also a stabilising controller satisfying the same level of closed loop performance
