摘　　要：针对开关磁阻电动机的高度非线性,提出SRM激励参数的在线调节控制策略。采用智能控制方法使驱动系统的性能指标转矩/安培最优的开通角在线调节;针对转矩脉动的关断角补偿;根据给定转速和电机实际转速的差值,通过模糊逻辑判断,推导出最佳参考电流值。仿真结果显示控制系统的激励参数自调节方案的有效性。To overcome the highly nonlinear characteristic of the SRM,the on- line control strategies are presented to automatically adjust the excitation parameters, the strategies are as follows,the intelligent adjustment of the turn- on angle to maximize the ratio of the average torque to RMS phase current, turn-off compensation to reduce torque ripple; fuzzy logic control to give the reference current based on speed error and its change. The simulation results show the effectiveness of the system.
