Robust H/sub /spl infin// filtering for LPV discrete-time state-delayed systems

摘要: This work examines the problems of robust H/sub /spl infin// filtering design for linear parameter-varying discrete-time systems with time-varying state delay. We present new performance criteria that depend on parameters and delay-varying magnitude using appropriately selected Lyapunov-Krasovskii functional. Then corresponding filter can be obtained from solution convex optimization in terms parameterized matrix inequalities, which solved via efficient interior-point algorithms. And admissible guarantees a prescribed noise attenuation level, relating exogenous signals to estimation error all possible vary compact set. A numerical example illustrates feasibility proposed methodologies.
