This paper presents the method of reducing torque ripple of brushless DC (BLDC) motor. The commutation torque ripple is reduced by control of the DC link voltage during the commutation time. The magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (PSO) algorithm analysis. The goal of optimization ...

In this paper, the Nonlinear Model Predictive Control (NMPC) technique is proposed for control of BrushLess Direct Current (BLDC) motors to address problem over-excitation, specifically in Electric Vehicle (EV) applications. This over-excitation increases overall energy consumption machine and eventually reduces vehicle’s driving range. The developed NMPC incorporates a nonlinear model BLDC mot...

The commutation process causes current ripple to be generated in the drive system of brushless DC (BLDC) motor. This, in turn, leads to output torque ripple. Mechanical vibration and acoustic noise are its influences which are undesirable phenomenon in some applications. A new method is presented in this paper which reduces torque ripple and commutation period in the entire range of motor speed...

The permanent magnet brushless direct current motor (BLDC), have been the main component in most of the Ventricular Assist Devices (VAD) development.
