Abstract

Abstract: A dynamic suppression method for commutation torque ripple by employing a quasi-Z-source network was proposed, which reduced the torque ripple dynamically during the speed adjustment process in brushless DC motors (BLDCM). The phase resistance was taken into consideration and the mathematics model for the system was established. To suppress the commutation torque ripples timely and effectively, U_up and t_up needed to be adjusted dynamically through the quasi-Z-source network while the speed and load changed. A simulation model to dynamically suppress the commutation torque ripple in BLDCM based on quasi-Z-source network was established by MATLAB/Simulink, and the feasibility was validated by experiments.
