中文摘要
      本文研究了基于滤波的无线传感器网络的H∞控制问题. 首先建立了无线传感器网络的模型, 然后使用稳态Kalman滤波器对多个传感器节点的输出信号进行滤波, 将滤波后的信号作为无线传感器网络系统的反馈输出, 并通过建模和分析得到带干扰的线性离散切换系统模型. 最后设计了切换控制器, 并基于Lyapunov函数给出了在任意切换条件下使该切换系统满足H∞控制的条件. 仿真结果验证了该方法和结果的可行性.
英文摘要
      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.
