摘要：鉴于无线网络控制系统在理论与实践两方面具有重要意义，考虑一类基于无线传感器网络实现的闭环网络控制系统，分析了无线传感器网络中采用的多跳通讯方式对网络延时的影响，提出了一种基于客户机—服务器模型的LQR输出反馈控制策略；利用线性矩阵不等式和切换控制系统理论，推导了系统的稳定性条件，给出了控制器的设计方法。实验结果表明了该算法的有效性。

Abstract: Aiming at the importance of wireless networked control system in practice and theory,  multi-hopping wireless communication and their effect on network-induced delay were analyzed for a class of networked control system wherein the control loop were closed through wireless sensor networks, and an LQR-output feedback control scheme based on a client-server architecture was proposed. The stabilizing conditions of the close loop control system were obtained and the LQR controller was designed through linear matrix inequality and switched control system theory respectively. The results of experiment show the effectiveness of the presented methods.
Key words: wireless sensor networks; networked control system; linear matrix inequality; switched control system
