Abstract :
This paper is concerned with H2/H∞ filtering of networked discrete-time systems with multi-channel packet dropouts. Considering multi-channel data packet dropouts in the sensor-to-filter, the random data packet dropouts of each channel was firstly described by a two-state Markov chain. Then the filtering error dynamic system was modeled as a Markov jump system with multiple modes. Based on the Lyapunov method and linear matrix inequality (LMI) technique, a sufficient condition for the existence of a filter is presented, and the designed filter enables the error dynamic system to be stochastic stability and to guarantee a prescribed H2/H∞ performance. Finally, numerical simulation confirms the efficiency of the proposed method.
