Sensorless control for PMSMs represents one of the main aspects of embedded systems because it allows the removal of sensors at the advantage of dimensions’ reduction and diminished maintenance. The Direct Flux Observer technique allows obtaining a measurement of the flux linkages of the motor phases, which are function of the electrical rotor position needed for motor driving, without the usage of current sensors. However, the measured signals are affected by noise. Therefore, a Sliding Mode Differentiator is used in order to perform reliable and robust to noise control of PMSMs. Simulation and experimental results are shown and discussed.
