模型预测控制在温度调节中的应用

The Application of Model Pre-Survey Control to the Temperature Adjustment

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。温度对象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,仿真和试用结果令人满意。

For the temperature control, the model is established according to the pulse response, and the next control value is calculated with pre-surveying value, thus the control speed is greatly increased. Pulse response of temperature process is easy to get on-line, and there is only one parameter for field tuning, so the controller is easy to operate. Both the simulated result and experimental results are satisfactory.
