随着飞机电气化进程的不断推进,永磁同步电机(PMSMs)因为优异的性能被广泛地应用于机上各种电驱动系统。而在电机矢量控制的诸多技术中,精确的转子初始位置辨识对其平稳起动与最大转矩运行意义重大。在对各种初始位置辨识方法进行分析和归纳后,从有位置传感器与无位置传感器2个方向,对永磁同步电机初始位置辨识方法进行了全面综述。首先,把有位置传感器的初始位置辨识方法总结为转子静止型与转子微动型2种,比较了各种有位置传感器辨识方法的异同点;然后,根据注入信号是否连续,将无位置传感器的转子初始位置辨识方法划分为高频电压注入法和脉冲电压注入法2大类,并选择脉振高频电压注入法对转子初始位置辨识效果进行了验证;最后,对永磁同步电机初始位置辨识方法的发展趋势进行了展望。

With the continuous advancement of aircraft electrification, Permanent Magnet Synchronous Motors (PMSMs) are widely used in various electrical drive systems on aircraft due to their excellent performance. Among the technologies of vector control, accurate identification of the initial rotor position is of great significance for the smooth starting and maximum torque operation for PMSMs. This paper provides a comprehensive overview of the initial rotor position identification methods for PMSMs from two perspectives: with and without position sensors. Firstly, the initial rotor position identification methods for PMSMs with position sensors are classified into two types: rotor standstill type and rotor micro motion type, and the similarities and differences of the identification methods of the rotor with position sensors are compared. Then, based on whether the injection signal is continuous or not, the initial rotor position identification methods for PMSMs without position sensors are divided into two categories: the high-frequency voltage injection method and the pulse voltage injection method. The pulsating high-frequency voltage injection method is selected to verify the effectiveness of rotor initial position identification. Finally, the development trend of initial position identification methods for PMSMs is discussed.
