Adjoint matrix decoupling prediction function control method for petroleum refining industry

The invention relates to an adjoint matrix decoupling prediction function control method for a petroleum refining industry. In the traditional method, control measure and control parameter depend on technicist experience completely, so that a control effect is bad. The method comprises the following steps of: building a adjoint matrix decoupling model based on the petroleum refining industry, digging out basic characteristics; building a prediction function control loop based on the adjoint matrix decoupling model; finally, computing parameter of the prediction function controller, and performing prediction function control for the object. The method builds an adjoint matrix decoupling prediction function control method for petroleum refining industry by measures such as data acquisition, procedure processing, prediction mechanism, data driving and optimization, and can effectively improve control precision and control smoothness. The method effectively reduces errors between ideal technological parameters and actual technological parameters, ensures that the control device is operated at the best state, and strictly controls technological parameters during a production process.
