无刷直流电机电流连续控制方法的研究与实现
Research and Implementation of a Continuous Current Brushless DC Motor Control Method
摘要
Abstract
A method for controlling brushless DC motor continuous current was accepted to suppress commutation torque ripple. The method was to control the winding current changes by a continuous and controllable method after a delay of 30°in Hall transition. And by changing the duty cycle of the PWM modulation,the on-phase current was gradually increased from 0 to the amplitude,the off-phase current was gradually reduced from the amplitude to 0,the constant-phase current keep the amplitude unchanged,thus the three-phase formed a continuously changing current waveform and the resultant current vector was a regular hexagon. It could be concluded from the experimental results that the method suppresses the commutation current ripple and achieves a better control effect.关键词
