Design and simulation for ball mill load control based on weighted fuzzy control algorithm

Due to the bad performance of ball mill load control by grinding sound in the blending process of sintering alumina production, a three-variable weighted fuzzy control algorithm is proposed, which control the mill load through grinding sound, bearing vibration and motor current. The three-variable weighted fuzzy algorithm, weighted fuzzy controller structure and its implementation are studied in this paper. The simulation with Matlab/Simulink shows the weighted fuzzy-control algorithm has better performance and robustness than PID control.
