H∞ filter design for discrete-time LPV systems

초록

A new design condition for H-infinity filter of discrete-time linear parameter-varying systems is addressed in this paper. The proposed method uses parameter-dependent Lyapunov functions and Finsler's Lemma to derive the filter design conditions in terms of linear matrix inequalities. The presented design method has an advantage that it is possible to obtain less conservative results compared to existing methods in the view of H-infinity performance and stability. The effectiveness and performance of the proposed filter design method are illustrated by numerical examples.
