“…An accurate estimator modelling allows for achieving the desired observer performance by means of a tailored observer regulator and for keeping the control bandwidth independent with respect to the motor working point [12]. The static gain of the observer, then the closed-loop observer bandwidth, varies as a function of motor inductances, thus motor parameters must be properly identified to compensate their variations [13].…”

The paper deals with a position sensorless control for synchronous motor drive with an ease tuning procedure and a reduced number of tunable parameters. The rotating high frequency (HF) signals injection is implemented and the elliptical shape of the HF induced current trace is fitted by means of the least square (LS) algorithm. The ellipse tilt is related to the rotor position and the latter is estimated by processing the fitted coefficients of the ellipse mathematical equation. The proposed LS algorithm processes the measured currents, without the need to filter them as occurs in conventional injection methods. Furthermore, no motor parameters are required to tune the proposed rotor position observer. The method was validated throughout several experimental tests performed on an interior permanent magnet (IPM) synchronous motor.
