Insensitive H∞ tracking control for discrete-time systems with coefficient sensitivity constraints

摘要：

The problem of designing insensitive H∞ output tracking controller for discrete-time systems is studied in a uni.ed framework by using the delta operator approach. Coefcient sensitivity functions of transfer functions with respect to controller coef.cient variations are de.ned, and the H∞ norms of the sensitivity functions are used to measure the sensitivity of the transfer functions with respect to controller coef.cient variations. Based on a novel bounded real lemma, a suf.cient condition for the existence of the insensitive controller is obtained in terms of linear matrix inequality (LMI) technique. Finally, a numerical example based on linearize model of F-18 aircraft is given to illustrate the effectiveness of the proposed method.
