摘　　要：以精馏塔精馏段温度控制为例,提出基于动态矩阵控制(DMC)算法的预测-PID双层控制方案,并通过MATLAB/Simulink联合仿真方法,对PID-PID、预测-PID两种双层控制系统进行仿真对比分析,得出预测-PID双层控制系统具有跟踪性能好、超调量小、调节时间短且抗干扰能力强的优点。Through taking the distillation section’s temperature control of the distillation column as an example,a prediction-PID double layer control scheme based on dynamic matrix control(DMC)algorithm was proposed and the MATLAB/Simulink co-simulation method was adopted to simulate and compare the PID-PID and predictive-PID double-layer control systems.The results show that,the prediction-PID double control system has advantages of good tracking property,small overshoot,short adjustment time and strong anti-interference ability.
