Commutation torque ripple is an important factor affecting the performance of brushless DC (BLDC) motor drives. In order to suppress this torque ripple, an alternating conduction control strategy between the two-phase and three-phase conduction mode has been proposed in this study. During the non-commutation periods, the conventional two-phase conduction mode is selected to drive the BLDC motor. While during the commutation period, the commutation torque ripple is reduced by employing an alternating two-phase and three-phase conduction mode. By calculating the duty cycle of the three-phase conduction mode, which indicates whether the rate of change in current in the incoming and outgoing phase is equal during the commutation interval, the commutation torque ripple is effectively reduced, while the current in the non-commutated phase is maintained constant. Simulation and experimental results show that the proposed method can suppress the commutation torque ripple efficiently, particularly at high rotational speeds of the motor.

“…According to reference [5], a single switch can be used to predict the output voltage and voltage compensation technology can be employed to account for torque at a constant speed, eliminating the need for a DC connection capacitor. To enhance the converter's efficiency, [6] and [7] propose a novel zero-energy thermonuclear component converter and interleaved boost converter respectively. These techniques effectively suppress torque ripple, but require additional topology circuits.…”

The traditional six-step commutation control method in brushless DC motors (BLDCM) often results in significant torque ripple, which limits its application in high-precision fields. This paper proposes a scheme that combines finite control set model predictive control (FCS-MPC) to suppress commutation torque ripple. The scheme utilizes an optimal duty cycle and optimal switch compensation state. By analyzing the mathematical model of BLDC motors, the causes of commutation torque ripple were identified. To maintain the slope of the non-commutation current unchanged, a discrete model was used to predict the non-commutation current at the next moment. The predicted current was then used to calculate the optimal duty cycle. To address the shortcomings of PWM regulation performance at high speeds, a switch insertion compensation strategy was proposed. The strategy selects the optimal switch insertion compensation state based on a cost function to offset the changes in non-commutation current. Furthermore, feedback compensation was incorporated to enhance robustness in the event of parameter mismatch. The effectiveness of this method was demonstrated through experimental and simulation results. INDEX TERMS BLDCM, model predictive control, torque ripple, cost function I. INTRODUCTION
