摘要

Sensorless control of Switched Reluctance Motor (SRM) drives based on phase inductance subregion is a relatively simple and obvious technique. However, its application has been reported only for choosing the suitable starting phase at standstill, and other sensorless techniques need to be combined for controlling the SRM during running conditions. In this paper, the validity of the method for sensorless control of SRM both at standstill and running condition, including phase-lacking fault mode and phase current sensor fault mode, are demonstrated. Experiments have been done for verification. The results show that this method possesses good starting and speed regulation performance, and good fault tolerant capacity under light load applications. This method does not require additional hardware, memory, and complex calculation, which is quite easy for implementation.
