MC控制在间歇反应釜温度控制系统中的应用

Batch Reactor has great inertia, long time delay as well as slow time-varying characters. The performances quality can’t be obtained by the traditional PID control. Thus, a temperature control system based on dynamic matrix predictive control is proposed, through the deeply research on time-delaying and nonlinear dynamic characters of batch reactor. The proposed control system not only overcomes the inaccuracy of reactor modeling, but also keeps the strong robustness and fast tracking performance effect of the predictive control algorithm. What is more, the disturbance could be rejected rapidly by the system, too. Simulation result shows that the control quality and the robustness of the system apparently are superiors to the general PID system.
