双三相永磁同步电机中对逆变器非理想特性鲁棒的开关频率信号注入无传感器控制

This article mainly describes a signal-injection sensorless control (SISC) method whose injection frequency is the same as the inverter's switching frequency. It has been known that the switching frequency SISC is vulnerable to nonideal characteristics of the inverter system. In this article, the current measurement noise and the deadtime effects are considered as the nonideal factors. The two fac...
