The Composite Method of Torque Ripple Restraining in Brushless DC Motor

Abstract:

Brushless DC motor generates parasitic torque ripple owing to its physical structure. The consequences deteriorate the performance of the drive in demanding applications. The mathematical model is analyzed. A fast toque control system employed which combines the current compensation and PWM_ON_PWM modulation. The effectiveness of the adaptive torque ripple compensation is demonstrated by experiments which is better than its using PWM_ON_PWM alone.
