基于PWM_ON_PWM调制方式的控制力矩陀螺框架电机驱动控制

Abstract

Abstract: Regarding the brushless direct current motor(BLDC) used in control moment gyro gimbal, the different pulse width modulation (PWM) modes of the full bridge drive circuit has different influences on the torque ripple of the control system. An analysis is presented on the different PWM modes from three aspects, including the electromagnetic torque ripple during the commutation, the torque pulsation during the non commutation, the application and improvement of the PWM mode, a conclusion is given that the best PWM mode for high precision control requirements is the PWM_ON_PWM mode, verification is obtained on the analysis result by numerical simulation.

Key words: control moment gyro (CMG), gimbal, pulse width modulation mode, torque ripple, PWM_ON_PWM
