Power Balance Control Strategy of Permanent Magnet Synchronous Motor of Belt Conveyor

Aiming at the problem of multi-machine power balance control long distance belt conveyor with double drum and three permanent magnet synchronous motor, method speed torque master slave motors driven by multiple is analyzed. According to properties coaxial rigid connection flexible drum, The strategy based on fuzzy Active Disturbance Rejection Controller (ADRC) proposed achieve purpose disturbance rejection improve stability system. simulation results show that can solve imbalance system motor. Compared traditional PID method, corresponding ADRC less than 300ms, deviation connected motor 0.1kW, 0.3kW. This effectively reduce synchronization error each has good robustness, realize distribution among motors.
