| 中文摘要 |
| 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. |
| 英文摘要 |
| 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 controller 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. |
