The main source of vibration/noise in BLDC motor based Electric Vehicle is the production of high torque ripple. In this paper, the operation of BLDC motor under different states are analyzed to determine the cause of torque ripple. To mitigate this problem a dual predictive controller is proposed for a BLDC motor. The controller is consisting of a cost function with 2 objectives. The first goal is to provide an adequate dc link voltage to reduce torque ripple, and the second is to estimate the best stator current for quick speed tracking. The simulation model of proposed control scheme is done in the MATLAB/Simulink environment. Compared with the traditional controlling methods, the simulation results shows that the proposed algorithm has suppressed the torque ripple drastically.
