摘要:开关磁阻电机具有显著的转矩脉动,从而降低电机的稳定性,影响其在控制领域的广泛应用。针对开关磁阻电机换相时,开通相绕组产生的转矩增加量无法补偿关断相瞬间的转矩减小量的缺陷,借鉴传统的转矩分配函数控制策略,在外环速度环采用不完全微分模糊PID产生参考转矩。仿真结果表明,优化后的策略有效地降低转矩脉动系数4.2471%,提升了SRM的稳定性。 关键词:开关磁阻电机;转矩分配函数;不完全微分;模糊控制 Abstract: The high torque ripple of switched reluctance motor reduces the stability of the motor and has a significant impact on its widely application in the area of control. Aiming at the problem that while the switched reluctance motor commutates, the increasing torque generated by the opening phase winding cannot compensate the reduction by the closing phase immediately, a new control strategy was proposed, in which the experience of traditional torque sharing function was used and the incomplete derivative fuzzy PID was used to generate reference torque in the outer ring of speed. Simulation results verify that the torque pulsation coefficient under the improved strategy is reduced by 42471%, which effectively improves the stabilization of SRM. Key words: switched reluctance motor; torque sharing function; incomplete derivative; fuzzy control
