摘要
针对网络控制系统(NCS)提出了自适应动态矩阵控制(DMC)算法。其基本思想是使用一个离散的延迟模型来预测对象的未来输出。给出了算法的推导过程和估计网络引入延迟的方法,基于TrueTime工具箱对比了不同网络条件下自适应DMC算法和传统DMC算法的性能。仿真结果表明自适应DMC算法能够适应网络条件的变化,为NCS提供更好的控制品质。
The adaptive Dynamic Matrix Control （DMC） algorithm was proposed for Networked Control System （NCS）. The main idea was using a discrete time-delay model tO predict future plant outputs. The derivation of the algorithm, as well as the estimation of the network-induced delay, was presented. Based on TrueTime toolbox, the adaptive DMC algorithm was compared with conventional DMC algorithm under different network conditions. The results show the proposed algorithm can adapt to various network conditions, and thus provides the better control performance for NCS.
