摘要：

In the network control system, the random network time-delay can usually deteriorate the control performance and stability of networked control systems. To solve this problem, this paper establishes the AR model for network time-delays and uses online and parameter self-tuning LMS algorithm to predict time-delay. Then adopting improved GPC based on state-space model to compensate the time-delay. Finally, simulation results show that this method has a good effect on time-delays compensation and has a good real-time because of the small amount of on-line calculation.
