Abstract:The brushless DC motor (BLDCM) has the outstanding shortcomings of torque ripple. A new hybrid control strategy based on DC link voltage control and fuzzy PID controller is proposed to suppress the torque pulse of the brushless DC motor. The circuit topology contains power. Factor corrected buck converter and inverter. The buck converter reduces commutation torque ripple by controlling the DC circuit voltage, and an inverter using a fuzzy PID controller and pulse width modulation (PWM) technology provides the appropriate current in the conduction region. The Buck converter reduces the commutation torque ripple by controlling the DC link voltage. The inverter uses the fuzzy PID and PWM technology to provide the current in the conduction region. This method can eliminate the torque ripple in the conduction region and weaken the torque ripple in the commutation region. The simulation results show that the strategy has a power factor correction function, which can effectively suppress torque ripple. Improve the robustness of motor operation.
