本文考虑前向和反馈通道均存在网络时延的网络化控制系统,提出了一种新的动态输出反馈控制器的设计方法。针对状态可测和不可测两种情况,整个设计过程采用不同的时延补偿机理,来主动地消除网络时延的影响。同时,讨论了闭环网络化控制系统的稳定性。最后的仿真实例表明了该方法的有效性。
This paper proposes a new method to design the dynamic output feedback controller for networked control systems (NCS) with communication delay in both forward and feedback channels. In order to remove the effects of the commu-nication delay according to one’s will, two different network delay compensation schemes are provided in two cases: the controlled plant whose state vectors can be measured and the one whose state vectors cannot be measured. Furthermore, another key part of this paper is to analyse the stability of the closed-loop networked control system. Finally, numerical simulation results show the effectiveness of the proposed method.
