Controller Reduction: Weights for Stability and Performance Preservation

Goddard P. J. and Glover K.

Presented at the 32nd CDC, 1993

Abstract

In this paper we investigate the design of reduced order controllers using an H infinity framework. Provided there exists a stabilising controller, K0, giving satisfactory closed loop performance we derive frequency weights such that if the infinity norm of W_2^{-1} (K-K0) W_1^{-1} is less than 1 then K is also a stabilising controller satisfying the same level of closed loop performance.
