Research on harmonic wave suppression model of underground mine local fan output using permanent magnet synchronous motor

Abstract

Permanent magnet synchronous motors (PMSM) have been widely used in the field of industrial servo control, especially in high-precision applications, and have begun to be put into use in the local mine fan system in our country in recent years. Harmonics can cause operational problems in the control system's associated electrical and electronic equipment. This article presents an algorithm to eliminate output harmonics of the PMSM motor controller based on multi reference frame (MRF) theory combined with low pass filter (LPF) and gives simulation results on Matlab/ Simulink when using that algorithm. From there, improve the efficiency of electricity use of local ventilation fans in underground mines.
