This invention relates to an energy consumption optimization method for special steel annealing furnaces based on improved nonlinear model predictive control, belonging to the field of intelligent control technology for special steel heat treatment. It solves the problems of lag and overshoot inherent in the PID controllers used in most existing annealing furnaces. Based on the law of conservation of energy, the formulas for annealing furnace heat loss, heating, and steel heat absorption, a nonlinear differential equation describing the furnace temperature is obtained. The current state and operating parameters are acquired. A physical information neural network is constructed based on the nonlinear differential equation describing the furnace temperature to predict the furnace temperature. Based on the predicted furnace temperature, current state, and operating parameters, an NMPC controller is used to obtain the updated valve opening. This invention enables real-time adjustment of the furnace temperature by a nonlinear model according to the current state and operating parameters.
