DECENTRALIZED ROBUST H-INFINITYCONTROL FOR DISCRETE-TIME SINGULARLARGE-SCALE SYSTEMS WITH PARAMETERUNCERTAINTY

摘要

The decentralized robust H-infinity control problem for discrete-time singu-lar large-scale systems with uncertainty in state and control matrices is considered. The uncertainty is elementary value bounded but not necessarily satisfies the so-called match-ing conditions. Based on the bounded real lemma of discrete-time singular systems, A sufficient condition for existence of decentralized robust H-infinity controller of uncertain discrete-time singular large-scale systems is presented in terms of matrix inequalities, and the feasible solutions to the corresponding matrix inequalities provide a parameterized representation of a set of decentralized robust H-infinity controller.
