基于线性正弦跟踪算法的PMSM无位置传感器研究
|
摘要
通过对脉振高频电压注入法下的内置式永磁同步电动机(IPMSM)模型进行分析,研究了一种改进的IPMSM无位置传感器控制策略。不同于传统高频信号注入法直接获取响应电流,该方法将线性正弦跟踪(LST)算法应用于高频响应电流中误差角的提取,可以省去幅值调制和低通滤波的环节。对LST算法的工作原理进行了分析,并对算法的稳定性进行了证明,基于该算法设计了线性正弦跟踪器。搭建了仿真平台,通过仿真分析验证了该方法的有效性,结果表明该方法能够快速准确得到转子位置信息。
Based on the pulse high-frequency voltage injection method,an improved interior permanent magnet synchronous motor( IPMSM) position sensorless control strategy was studied. Different from the traditional pulsed high-frequency signal injection method of high-frequency response current acquisition,the method applied the linear sinusoidal tracking( LST) algorithm to the extraction of the error angle in the high-frequency response current,eliminated the amplitude modulation and low-pass filtering process. A linear sinusoidal tracker was designed and the stability of the LST algorithm was proved. The simulation platform was built. The effectiveness of the method was verified by simulation analysis.The results show that the method can obtain the rotor position information quickly and accurately.
