H-infinity control of wireless sensor networks with filtering
带滤波的无线传感器网络的H_∞控制

We investigate the H-infinity control of wireless sensor networks based on filtering. First we propose a model for the wireless sensor networks; and then, we apply the steady-state Kalman filter to the output signals of multiple sensor nodes. The obtained signals are considered as the feedback output of wireless sensor networks. By modeling and analyzing, we develop the switching model of the linear discrete-time system with disturbances. Finally, the switching controller is designed. By using Lyapunov function, we develop sufficient conditions of H-infinity control for the linear switched systems with any switching rule. The simulation demonstrates the feasibility of the method and results obtained.
