Abstract: In order to solve the problem of material’s falling or rolling which occurs in starting and braking of high-inclination belt conveyor driven by multi-motor, a fuzzy control algorithm for high-inclination belt conveyor driven by multi-motor was established, and overall control model of high-indiration belt conveyor, speed setting algorithm of belt conveyor, and a fuzzy PID parameters self-tuning algorithm for power balance were introduced. The application shows that the fuzzy control algorithm can automatically adjust speed of belt conveyor according to real-time changes of coal traffic, it makes speed control error lower than 2% and power control error lower than 2.5%, enables power of four drive motors tends to the same, and achieves reliable, safe and energy-saving operation of belt conveyor driven by four motors.
