Abstract

This paper considers the design of robust H∞ filtering problem for switched stochastic discrete time-delay system With missing measurements via switched Lyapunov function approach. Attention is focused on the design of an exponentially stable filter guaranteeing a prescribed noise attenuation level in the H∞ sense and missing measurements probability. By using switched Lyapunov functionals, some sufficient conditions in terms of linear matrix inequalities (LMIs) are obtained. Finally a numerical example is provided to demonstrate the effectiveness and applicability of the proposed design approach.
