Simultaneous fault detection and controller design for networked-based discrete-time switched systems with time-varying delays

摘要: This paper studies the problem of simultaneous fault detection (FD) and control discrete-time switched systems with time-varying delays under an arbitrary switching signal in a network communication. The missing phenomenon is assumed to occur, communication links for sensor-to-controller controller-to-actuator, where probability packet dropouts governed as two different mutually independent Bernoulli distributed white sequences known conditional distributions. main attention focused on designing robust filter (FDF) such that estimation error between residual minimized exponential way at same time closed-loop networked system exponentially stable mean-square sense. controller design converted into H ∞ filtering problem. By multiple Lyapunov-Krasovskii functional (LKF) average dwell-time scheme, novel delay-dependent sufficient conditions are developed ensure resulting optimized disturbance attenuation level. solution parameters controllers filters characterized terms feasibility convex optimization A numerical example given illustrate effectiveness obtained results.
