动态矩阵控制在电阻炉温度控制系统中的应用

Application of DMC in the Temperature Control System of Electrical Resistance Furnace

通过对电阻炉动态对象特性的研究以及预测控制方法的改进，比较了动态矩阵控制和PID控制在电阻炉温度控制系统中的应用效果．仿真结果表明：DMC不但克服了建模的不精确性和参数的时变性，而且根据给定的期望曲线，实现了比PID控制更令人满意的性能指标．

With the research of dynamic characteristic of electrical resistance furnace and the improvements of MPC in detail, the effects between DMC and PID in the temperature control system of electrical resistance furnace was compared. The results confirmed that DMC not only overcomes the inaccuracy of the models and the variability of the parameters, but also achieves better performance index than PID in accordance with the expectation of given curve.
