Delay-dependent L2-L∞ filtering for stochastic networked control system with missing measurements

This paper deals with a delay-dependent L-2-L-infinity filter design problem for networked control system with stochastic perturbation, nonlinearities and missing measurement. The missing measurement is described by a binary switching sequence satisfying a conditional probability distribution. A new model is proposed to describe both the network conditions and missing measurements of networked control systems in a unified framework. The sufficient conditions for the existence of the filter are given, thus, guaranteeing the filter error system exponentially stable in the mean-square sense and the L-2-L-infinity performance satisfies a prescribed level. Numerical example is given to illustrate the effectiveness of the proposed method.
