针对一类基于无线传感器网络实现的无线网络控制系统,分析了闭环控制系统中网络延时的组成,着眼于减少网络延时对控制系统性能的影响,从网络通讯的角度出发,提出了一种实现最小传输延时的路由协议算法,详细叙述了路由协议算法的设计和实现。在此基础上,对该路由协议算法的性能进行了验证,实验结果表明了该路由协议算法的有效性。
Aimed at a class of wireless networked control systems based on the wireless sensor networks, the sources of networkinduced delay were identified for closed-loop system. With an aim to decrease the impact of the network-induced delay on the system, from the viewpoint of the wireless network, a novel routing algorithm that can minimize the total round-trip time delay for wireless networked control system was presented and the implementation of the algorithm was recited in detail. Furthermore, the effectiveness of the routing algorithm was validated with the experiment.
