模型预测控制(MAC)用脉冲响应建立预测模型,按预测值反馈计算下一步控制量,因而可大大提高控制速度。温度过程的脉冲响应容易在线测取、现场整定参数只有一个、使用方便,因此可以设计成通用快速温度调节器。仿真和试用结果令人满意。
Model predictive control (MAC) uses impulse response to establish the predictive model, and calculates the next control quantity according to the predicted value feedback, which can greatly improve the control speed. The impulse response of the temperature process is easy to measure on-line. There is only one parameter set in the field, easy to use, so it can be designed as a universal fast temperature regulator. Simulation and trial results are satisfactory.
