零点

In this paper, an improved sensorless control strategy, which is based on the detection of zero crosspoints of back-EMF, is proposed. In this method, only one feed back signal is needed to sense terminal voltages and no motor neutral line is required. The phase shifter errors in traditional methods are eliminated.

本文同时提出了一种改进的无位置传感器检测方法，这种方法基于反电势过零点检测的基本原理，采用单路位置反馈信号，无须引出电机中性线，硬件结构简单，消除了传统检测方法中由于深度滤波产生的相移和误差。
