A new method of modeling discrete networked control systems with both the time-varying delay and packet loss was presented in this paper.The network-induced delay is time-varying and it can be smaller or larger than one sampling period.The feedback controller was designed by free-weighting matrices method and Lyapunov-Krasovskii functional to make the networked control system asymptotically stable.And sufficient conditions were derived.A numerical example is given to illustrate the effectiveness of the prop... 相似文献

随着控制技术的飞速发展,把通信网络引入到传统的控制系统实现闭环控制成为人们日益关注的课题。针对网络控制系统的运行特点,设计并实现了一个网络协同试验仿真平台,可为网络控制系统的理论分析和设计方法进行有效的验证。根据网络协同控制系统的特点,给出了仿真试验平台的设计思想和结构,介绍了RTX的实时功能原理和RT-TCPIP的实时通讯机制,在此基础上,讨论了基于RTX的网络协同控制系统仿真平台的软件设计和实现方法。最后通过一个试验实例验证了该仿真平台设计的有效性。对实时性要求高的仿真系统具有一定的参考价值和指导意义。 相似文献
