Optimal H Control of Networked Systems Based on Dynamic Scheduling


Abstract:
A new approach to design optimal H controller based on dynamic scheduling is proposed for networked control systems with communication constraints. The closed-loop networked control system is modeled as a discrete-time switched system with several subsystems by using communication matrixes and indicator function. Based on Lyapunov stability theory, sufficient conditions of mode-dependent robust stabilization are derived and an output feedback controller for networked control system is designed. By applying analysis method of switched system, a dynamic scheduling policy is designed based on real-time status to achieve the stabilization of networked control system. Finally, an illustrative example is provided to demonstrate the effectiveness of the proposed method.
