摘要
Abstract
This paper studies the permanent magnet synchronous motor （PMSM） direct torque control （DTC） system, DTC has drawbacks that the ripples in torque are relatively higher at low speed. The thesis analyzes the reasons of DTC system for the existence of torque ripple, and uses the nonlinear perpendicular flux observer with compensation feedback, solves the problems associated with traditional flux observer, and studies the effect of zero-voltage vector to the torque, uses the switch table that add the zero-voltage vector. Through analyze the results of simulation, it can reduce the torque ripple.关键词
