一种针对延迟的时间标记动态矩阵控制

A Time-stamped Dynamic Matrix Control for Delays

由网络引入的通信延迟能导致系统性能退化甚至不稳定,针对这种网络控制系统中的延迟,引入时间标记的动态矩阵控制算法(TSDMC),建立随同时间标记的通信延迟模型。通过时间标记测量网络延迟,在线校正系统的阶跃响应系数和控制系数,并给出了算法的推导过程。根据仿真的确认,这种新的算法能得到比传统动态矩阵控制算法更好的控制性能,改进了网络控制系统可靠性。

The communication delay introduced by the networks can lead to performance degradation and even instability. To address network-induced delays, a time-stamped dynamic matrix control （TSDMC） algorithm which uses a communication delay model to improve reliability over network control systems is proposed. The network-induced delays are measured by a time-stamp method, based on which the step response coefficients and control coefficients ate corrected in each sampling period and the algorithm derivation is given. Simulative validation of this new algorithm resulted in improved performance and stability over traditional dynamic matrix control （DMC）.
