Coordinate design of dynamic scheduling and H-infinity control for networked control systems with communication constraints
具有通信约束的网络控制系统动态调度与H_∞控制协同设计

A coordinate design scheme of the try-once-discard (TOD) dynamic scheduling strategy and the robust Hinfinity controller for a class of networked control systems with communication constraints and random time-delay is proposed. Considering communication constraints and the random time-delay, we model the networked control system (NCS) as a discrete-time switched system with parameter uncertainties. Using the Lyapunov function and switched system theory, we develop the design procedure for the robust H-infinity controller under TOD scheduling strategy to maintain the asymptotic stability of the closed-loop system. A simulation example demonstrates the efficiency of the proposed method.
