| 摘 要： | 开关磁阻电机噪声主要是其径向力波使二阶振型模态产生偏移引发的.针对开关角是开关磁阻电机中两个最为重要的控制参数的特点,提出了开关磁阻电机电压PWM控制方式下开关角的两次在线寻优方法.寻优原理以径向力激发的二阶振型模态最高噪声声级最小为目标,并依据寻优步长不同实行两次优化搜索.仿真结果表明,两次在线寻优的开关角能使开关磁阻电机运行时激发的二阶振型模态最高噪声声级显著降低,从而使得整体噪声减小.

| Abstract: | Noise of switched reluctance motors is mainly induced by radial force's exciting on 2nd vibrating mode.According to the feature that switching on and off angles are two most important control parameters in switched reluctance motors,twice online optimization of these two angles was proposed under voltage PWM control mode.This principle aimed to minimizing highest noise level of 2nd vibrating mode excited by radial force,and twice optimizations were performed due to different steps.Simulation indicates that ... |
