Abstract:Aiming at the problems of poor anti-interference ability and tedious parameter adjustment of traditional PID controller, a pray level predictive controller is proposed. The gray prediction algorithm is analyzed in detail in theory and modeled mathematically. The parameters of the controller are adjusted by the steepest gradient method, and the controller with adaptive parameters is designed. The BLDC motor used in flywheel is modeled accurately, and the motor control simulation model based on the gray prediction is designed. The different performances of the two controllers under normal acceleration and disturbance are analyzed by simulation, and the superiority of the Gray Prediction Controller in regulation effect and stability is verified.
