DMC的主要特征是预测模型采用阶跃响应特性建模 设计过程中固定格式:用二次型目标函数决定

控制量最优值增量序列 自校正动态矩阵控制等多种算法 参数调整:用改变二次型目标函数中的权系数

阵来实现.-With the research of dynamic characteristic of electrical resistance furnace and the imp rovements of

MPC in detail, the effects between DMC and P ID 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 P ID in accordance with the

expectation of given curve.
