Co-design of dynamic scheduling and H-infinity control for networked control systems

A novel co-design scheme of TOD dynamic scheduling strategy and the robust H-infinity controller for a class of networked control systems (NCSs) with communication constraints and random time delay is proposed in this paper. The NCSs with communication constraints and random time delay is modeled as a discrete-time switched system with parameter uncertainties, and a procedure for robust H-infinity controller design under TOD scheduling strategy based on the Lyapunov function and switched system theory is proposed to guarantee the asymptotic stability of close-loop system. Finally, a simulation example demonstrates the efficiency of the proposed method.
