Abstract:In the network control system, uncertain factors such as network delays can usually deteriorate the control performance and stability of networked control systems. Therefore, a new network control algorithm is proposed. First, the auto regressive model for network time delays is established, and parameter self-tuning LMS algorithm is used for online prediction. Then improved generalized predicive control based on state-space model is adopted 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, at the same time, the method has good robustness according to interference and data loss.
