DMC控制由于具有对模型精度要求低，控制精度高鲁棒性强等优点可有效的克服过程的不确定性、非线性和关联性，并能方便的处理过程被控量和操纵变量中的各种元素。所以对该系统应用DMC控制方法进行MATLAB仿真。-DMC control accuracy because the model has low and high control precision and strong robustness advantages of the process can effectively overcome the uncertainty, nonlinear, and relevance, and to facilitate the processing and manipulation of variable charges in the amount of various elements. Therefore, application of the system control method DMC MATLAB simulation.
