Abstract

This paper presents a novel space-vector current-control strategy to minimize the torque ripples in brushless DC Motor (BLDC) motor. For BLDC motors, torque ripple, is an important origin of vibration, acoustic noise and speed fluctuation. The current ripple, created due to the stator winding inductance and deviation of back emf, leads to generation of ripple in the torque and prevents the usage of BLDC motor in a precise servo drive system. The paper includes MATLAB/SIMULINK results of conventional, unipolar, bipolar current control algorithms, varying input voltage method and a novel space vector current control method. The comparison of simulation results reveals that the proposed technique is effective in reducing the torque ripple and improves the system performance. The validity and practical applications of the proposed control scheme are verified through the experimental results. The proposed method for torque ripple reduction is validated by reconstructed torque waveforms.
