H-infinity control for a class of networked control systems with multiple packet transmission
一类多包传输网络控制系统的H_∞鲁棒控制

The optimal H-infinity control problem for a class of networked control systems (NCS) with multiple packet transmission is studied. For networked control systems with clock-driven sensors and event-driven controllers and actuators, when the time-delay is uncertain and less than one sampling period and the external disturbance is limited, the modelbased control scheme is proposed, and the sufficient condition of the existence of H-infinity control law is derived by using Lyapunov theory. The optimal H-infinity controller law is obtained through solving a convex optimization problem constrained by matrix inequalities. A numerical simulation example shows the validity of the proposed method.
