The paper deals with control of Permanent Magnet Synchronous Motor (PMSM) without a rotor position sensor. In the low and zero speed region, saliencies are utilized to obtain information about position. Self-sensing techniques employ high frequency (hf) signal injection excite saliencies. proposed algorithm enables tracking saliency allows PMSM at speed. theoretical assumptions were experimentally verified including initial detection.
