Robust H∞ filtering of nonlinear switched system with time-delays

This paper investigates robust H
∞
filtering problem for a class of nonlinear switched systems with time-delays. Based on piecewise Lyapunov function and the average dwell time approach, sufficient conditions for the existence of the filter are derived using a set of linear matrix inequalities (LMIs), and all solutions including the filter parameters are also obtained. Finally, a numerical example is provided to demostrate the effectiveness of the proposed method.
