摘要介绍了高频电压信号注入法在市面贴装永磁电机位置跟踪中的应用。这类机器固有的低显着性带来了困难，并使信号调节变得非常关键。本文采用空间调制仿形(SMP)的方法来获取机床的磁信号，以校正位置信号中的周期性误差。实验结果表明，该技术在提供高质量位置信号方面是有效的。然后利用这些来提供良好带宽的闭环无传感器位置控制。
Abstract This paper presents the use of hf voltage signal injection for tracking position in an off-the-shelf surface mounted permanent magnet machine. The inherent low saliency of this type of machines presents difficulties and makes the signal conditioning highly critical. In this paper the method of space-modulation profiling (SMP) is used to obtain a magnetic signature of the machine in order to correct for periodic errors in the position signals. Experimental results illustrate the effectiveness of this technique in providing position signals of high quality. These are then exploited to provide closed loop sensorless position control of good bandwidth.
