本文提出一种基于动态矩阵控制(DMC)算法预测特性的新型PID控制方法.在考虑将来的输出期望偏差罚函数最小的前提下,由DMC计算出控制变量的值.继而构造基于DMC的预估器用以预测将来时刻的系统输出.根据将来时刻的多步预测偏差,PID控制器产生当前时刻的实际控制增量.文中也给出了基于DMC的预估器及PID控制器的参数整定方法.仿真结果表明,与常规的PID控制和DMC控制相比,所提方法具有良好的控制性能,扰动抑制尤其优良.

This paper proposes a novel PID control scheme equipped with predictive property based on dynamic matrix control(DMC)algorithm.DMC computes the manipulated variable through minimizing a cost function of expected future errors.Next,a DMC-based predictor is constructed to predict the output values at the future time instant.The predicted future errors are used in a PID controller to generate the actual control actions.The DMC-based predictor and the PID con-troller are well tuned to provide the design parameters.Compared with the conventional PID and DMC control,simulation results demonstrate the better output responses,particularly in disturbance rejection performance.
