Simulation Analysis of Permanent Magnet Synchronous Motor System of Belt Conveyor

In view of the present situation of the permanent magnet synchronous motor of the belt conveyor in the mine transportation equipment,this paper analyzed the advantages and disadvantages of five kinds of speed control system orientation forms:vector control,direct torque control,adaptive control,sliding mode variable control and predictive control.At the same time,it used MATLAB simulation software to simulate the permanent magnet synchronous motor system,and obtained that the speed response of feedforward decoupling control speed response was more sensitive,solved the torque ripple problem of PI control speed response,and improved the stability of the system.The control of the current stability of the motor and the prediction of the system module can be realized by using various control methods synthetically,which provides convenience for the belt conveyor to adapt to different working environment.
