Knowledge-based predictive control method, predictive controller, device and medium for multi-physical field coupling large-scale industrial system

Abstract

The application discloses a knowledge introduction predictive control method for a multi-physical field coupling large-scale industrial system, a predictive controller, equipment and a medium, and the method comprises the following steps: acquiring the influence relationship between variables of the multi-physical field coupling large-scale industrial system by using an extended convergent cross-mapping algorithm; taking the acquired influence relationship between variables as prior knowledge to construct a predictor in the predictive controller; then embedding the predictor into a loss function of the predictive controller to establish a knowledge-guided predictive controller; and performing predictive control on the multi-physical field coupling large-scale industrial system by using the established predictive controller and according to current state variable values of the multi-physical field coupling large-scale industrial system. The application realizes accurate control of the system state by extracting the influence relationship of the observed variables in the system and integrating the influence relationship into the predictive model of the system as prior knowledge.
