摘要
针对无位置传感器内置式永磁同步电机(interior permanent magnet synchronous machine,IPMSM)全速域运行,传统的基于转速或位置信息融合的复合控制方法运算复杂度高、实现较为困难的缺点,该文提出一种基于标幺化位置误差信息融合的单Luenberger位置观测器复合控制方法。低速(零速)域和中高速域分别采用方波电压注入法和反电动势模型法获得标幺化位置误差信号;过渡区域通过速度信息对标幺化位置误差信号进行加权融合,采用单Luenberger位置观测器实现转子位置、转速实时观测。该复合控制方法能够实现IPMSM无位置传感器控制全速域运行,有效降低运算复杂度和观测器设计难度,算法实现较为简单。最后,通过2.2k W IPMSM无位置传感器矢量控制系统验证了所提出复合控制方法的有效性和实用性。
With regard to the position sensorless control at whole speed range for interior permanent magnet synchronous machine （IPMSM） drives, existing speed or position combination based hybrid control methods suffer from the implementation problem due to high computational complexity. This paper presented a single Luenberger position observer based hybrid control method using normalized position error signal combination. The square-wave voltage injection and the back electromotive force （EMF） model based methods were adopted to extract the normalized position error information at low- （zero-） and middle- to high-speed range respectively, And the normalized position error information was combined through the speed dependent weighted function. The single Luenberger position observer was utilized to estimate the rotor position and speed. The proposed hybrid control method can guarantee the position sensorless control at whole speed range with low computational complexity and easy-to-implement structure. Experiments on a 2.2kW IPMSM sensorless vector controlled drive have been carried out to verify the effectiveness and practicability of the proposed scheme.
