Flying Start of Permanent Magnet Synchronous Machine Drives based on Variable Virtual Resistance

In this article, a flying start method for sensorless-controlled permanent-magnet-synchronous-machine (PMSM) drives based on a variable virtual resistance is proposed. In the proposed method, the inverter imitates variable resistance, this is used to suppress the inrush current and to regulate the small estimation current. Afterward, the speed and position of the motor are identified using the est...
