摘要基于凸极效应,注入高频电压信号,从高频电流响应信号中解调出转子位置信息,实现电机的无位置传感器运行。基于旋转信号和脉振信号的两种高频注入法的原理介绍,综述了交叉饱和、AD采样量化误差、滤波器相位滞后、多重凸极等对控制系统精度的不良影响,从控制算法和电机本体设计两个方面总结了减小误差的措施。结合其它控制方法展望了无位置传感器电机控制系统的发展方向。 Based on the machine saliency property,a high frequency carrier voltage signal was injected into the machine,and the corresponding position-dependant carrier current response was used to extract rotor position information for sensorless control.Principles of rotating and pulsating signal injection based sensorless control methods were introduced,and the parasitic effects of cross-saturation,AD conversion quantization error,phase lag of filter and multiple saliency effects on sensorless control were discussed.In order to improve the performance of sensorless position estimation,some measures including appropriate control algorithm and machine design can be taken.Finally,the trends of sensorless control were discussed together with some new control strategies.
