New Results on H∞ Filter Design for Continue-Time Systems with Time-Varying Delay

This paper proposes a class of H∞ filter design for continue-time systems with time-varying delay. By using the Lyapunov functional function approach, some delay-dependent stability conditions can be obtained for the asymptotical stability of the H∞ filter systems, which are expressed as a set of Linear Matrix Inequalities (LMIs). Finally, a numerical example is given to demonstrate the effectiveness and the merit of the proposed method.
