PID control is the most practical application of the most widely used industrial process control strategy, while their study has yielded fruitful results. In the industrial process, more than 95%of the controller is PID controller. Especially since 1993, due to the development of modern control theory divorced from the actual engineering and modern industrial process

In traditional methods, some dynamic performance indicators, used for analyzing the system, such as overshoot, adjusting time and peak time, can reflect the dynamic performance well, but they are only suitable for the low-order system. When designing the controller based on these performance indicators, it is necessary to reduce the characteristic equation order and change

Model Predictive Control (MPC) was introduced in the late 1970′s. It has become an established control technology in the petrochemical industry. The most concern in application is not the form of the model but function. Dynamic Matrix Control (DMC) is a predictive control algorithm based on step response of the object model. This algorithm does
