摘要
近年来,网络控制系统得到越来越多的关注,其主要挑战之一在于控制环中的网络时延对其影响;网络时延会降低网络控制系统的性能,甚至使系统不稳定;目前,大多数学者只研究了网络时延小于采样周期时对控制系统的影响,而网络控制系统中的大时延更加复杂,同时也更加难以处理;文章论述了带有大时延的网络控制系统的现有的研究方法,并指出这种问题的其它可能的研究方法。
Networked Control System （NCS） has gained increasing attentions in recent years. One ot the major challenges is the network --induced delay effect in the control loop. Network delays can degrade the NCS performance and even destabilize the system. A lot of scholars only focus on studying the situation under which network delay is less than one sampling period. Large delay in NCS is more complicated and more difficult to handle. The recent study methodologies of NCS with large delays and some other possible study methodologies for this problem are presented.
