时滞系统方法的网络控制系统的研究

针对普遍存在的采样器和零阶保持器异步这一现象，研究了该类网络控制系统的状态反馈控制问题。首先，以事件驱动的零阶保持器的更新时刻为时间标识，并考虑到网络的诱导时延和数据丢包，建立网络控制系统的采样闭环模型，并转化为状态中连缀着两个时滞变量的时滞系统。然后，利用相应的时滞系统方法，对闭环网络控制系统进行了稳定性分析和控制器综合。最后，通过仿真实例验证了所得结果的正确性。

Delay system approach to research of networked control systems

This paper deals with the problem of state-feedback control for Networked Control Systems ( NCSs) with asynchronous occurrence of the sampler and the Zero-Order Holder ( ZOH).Firstly,based on the updating instants of the event-driven ZOH,the sampled-data NCSs with consideration of both the network-induced delay and data packet dropout are formulated,from which a time-delay system with two additive delay components is developed.Subsequently,by making use of the delay system approach,the stability analysis an...
