Exponential $H_{\infty }$ Filtering for Singular Markovian Jump Systems With Mixed Mode-Dependent Time-Varying Delay

This paper is concerned with the exponential H_∞ filter design for a class of continuous-time singular Markovian jump systems with mixed mode-dependent time-varying delay. By constructing a new Lyapunov-Krasovskii functional and utilizing some advanced techniques, a less conservative delay-dependent bounded real lemma (BRL) is obtained in terms of linear matrix inequalities (LMIs), which guarantees the considered system is exponentially admissible with H_∞ performance. Based on the BRL, the H_∞ filtering problem is solved and an explicit expression of the desired filter can be given. Two numerical examples are presented to illustrate the effectiveness and the potential of the proposed techniques.
