Abstract:

Brushless DC motors are most utilized in areas of aerospace and electric vehicles. They offer great efficiency, compact size, and superior power density. However, the BLDC motor’s torque output ripples provide significant challenges. Torque ripple causes undesirable vibrations, acoustic noise, and reduced performance. The main problem addressed in this article is minimizing torque ripple while achieving precise speed control. The proposed solution to the problem stated here is the Field-Oriented Control (FOC)-based speed control strategy. FOC enables smooth torque production and improved dynamic performance as opposed to typical trapezoidal control methods. The paper involved mathematical modeling of the BLDC motor using Clarke-Park transformations. Space Vector Pulse Width Modulation (SVPWM) is utilized to produce pulses to excite the stator coil. The FOC algorithm was executed in MATLAB/Simulink, and the system has been tested for differing load conditions. Important parameters, such as speed and current response, were analyzed. The ripple percentage of the torque output was compared against the IEEE std. 1812-2023 to prove the effectiveness of the FOC control loop. The results displayed that the FOC system significantly reduced ripple in torque output and thus improved the efficacy of the motor. In conclusion, the FOC strategy proved to be highly effective. It outperformed the six-step commutation strategy with respect to the torque ripple reduction and overall performance. Hence, proving the value of this method of control in applications like electric vehicles.
