| 中文摘要 | 针对简化磁链法开通角和关断角无法灵活且精确控制的问题,限制SRM(swithed reluctance motor)效率和高速运行性能,根据不同转速,提出实时调整开关角的无位置检测控制策略,通过建立电机有限元仿真模型,计算得到样机不同转子位置磁链模型。为提高角度位置控制精确度,针对SRM磁链模型的特点,给出参考磁链选取原则,在此基础上,根据不同转速实时调整开关角,实现SRM变角度位置控制。为验证提出的无位置控制策略的有效性,分别选取低速和高速样机进行试验。结果表明,提出的无位置检测法适用于低速和高速SRM,具有较高位置估算精确度。; Turn-on angle and turn-off angle are not flexibly and precisely controlled,which limits the motor efficiency and performance at high speed. Sensorless position detection strategy was proposed with adjusting switched angle in real-time according to different speed. Flux linkage models at different positions were calculated by using the FE model. In order to improve angle position control precision,the principle of selecting reference flux linkage was presented based on characteristics of flux linkage model of SRM.On this basis,the angular position control of SRM was implemented by adjusting turn-on and turn-off angle in real-time at different speed. To verify the validity of the sensorless position detection strategy,a low-speed and high-speed prototype were used. The tests verify that proposed control strategy is suitable for low-speed and high-speed SRM and rotor position estimation precision is high. |
