Abstract:
This study highlights the impact of an universal Phase Locked Loop (PLL) parameters variation on PMSM position estimation at low speeds. Indeed, the PLL parameters variation impact on the PMSM rotor position estimation performance and robustness cannot be neglected anymore. For this purpose, the study presents the theory and simulation results of a demodulation scheme applied to Sensorless PMSM control based on the Pulsating Voltage Injection (PVI) technique. Comprehensive simulations, carried out under MATLAB/SIMULINK®, are discussed according to the variation of the PLL proportional and integral parameters.

Key words:  Demodulation scheme, low speeds, Permanent Magnet Synchronous Motor (PMSM), Phase Locked Loop (PLL), Pulsating Voltage Injection (PVI) technique, rotor position estimation,
