| 摘 要： | 针对工业生产过程大多为多输入多输出非线性系统,干扰因素多,耦合作用强,常规控制方法难以获得满意控制效果的特.提出一种基于动态矩阵控制(DMC)的多模型控制方法,采用误差指标切换函数作为切换准则,根据其最小值来选择与实际最接近模型,并将基于此模型的控制器切换为当前控制器.结合目标函数解耦方法,在模型中考虑其他通道输入对当...

| Abstract: | To the feature of the most industry processes with multiple-input multiple-output,disturbance and coupling,which is difficult to get satisfied effect by the conventional control methods,a multi-model control method based on the dynamic matrix control(DMC) is proposed.The model best matching the current dynamics of the system is chosen,and the corresponding controller is applied to the system based on the switching index function.Based on the objective function decoupling method,the effect of the input of ot... |
