Sensorless control method of IPMSM with current derivative information of q-axis without high frequency component injection at low speed region

Various methods have been proposed to identify the flux position in an interior permanent magnet synchronous motor (IPMSM) without the use of mechanical sensors. To achieve this, a method that uses both the back electromotive force (EMF) and the saliency to identify the flux position in the IPMSM without the injection of high-frequency components at low speeds has been reported. We propose the extended method by controlling q-axis current derivative during zero voltage vector.
