Research on Coal Mill Control based on Adaptive Neural Network Fuzzy PID

Taking the identification results of the steel ball coal mill in Heng feng Power Plant as the research object, a simulation model of the coal mill control system of the adaptive neural network fuzzy PID was built based on the MATLAB/Simulink platform, and the fuzzy rules were trained and learned through the adaptive neural network to improve the coal mill outlet temperature control, inlet negative pressure control and load control strategies.The simulation results show that the adaptive neural network fuzzy PID control optimization effect is obvious. Under 50% working conditions of the coal mill, compared with the traditional PID regulation and fuzzy PID regulation systems, the stabilities are increased by 57.96% and 33.70% respectively; the adjustment speeds are increased by 43.88% and 31.38% respectively; the steady state errors are reduced by 95.41% and 89.33% respectively.
