An online delay?evaluation approach, namely average delay window(ADW) is introduced for networked control systems, which can characterize the time delays without any synchronized clock in the network and prior assumptions about time delays.

• 从网络控制系统的实际应用出发,在不附加网络同步时钟和对时延特征的离线假设下,运用通讯技术中的网络协议对网络时延进行在线估计;
