“…The mathematical model for a salient PMSM in stationary frame requires high computation time due to its complexity. If we admit an incertitude over the motor's inductances, one can suppose L d = L q = L s , which leads to an EKF using the non-salient model of the synchronous machine [6], [8], and thus reduce the complexity. This model is further presented in eq.…”

“…In the case of a permanent magnet synchronous machine (PMSM), this methods rely on spatial magnetic saliencies of the machine that provide position-dependent harmonics. Nevertheless, these methods are suitable on a limited speed range (standstill and low-speed); for higher speeds, it is common to use a transition algorithm [6], [7] in order to switch the estimation source to a high speed dedicated algorithm, based on back-EMF estimation, like the Extended Kalman Filter (EKF).…”

Sensorless control for electrical drives is still a challenge in the low-speed and standstill region. Solutions that inject a high frequency signal in order to generate positiondependent harmonics are well known for their good performance in this particular speed range. The possibility to combine signalinjection techniques with model-based observers could be a solution for sensorless control over the whole speed range.In this paper, a pulsating vector carrier signal injection is used with two different estimation methods. First method is based on the commonly used filtering and demodulation associated to the pulsating carrier method, and for the second method, an injection-based Extended Kalman Filter is proposed in order to estimate the rotor position. This two methods are analysed, we concentrate on: parameter tuning, transitory response and noise attenuation. The analysis is supported by experimental measurements obtained on a salient-pole permanent magnet synchronous machine. The results show the satisfactory performance of both methods and the potential to use the proposed injection-based Extended Kalman Filter from standstill to the high-speed region.
