Abstract (en)
[origin: WO2020016002A1] The invention relates to a method for estimating the speed and position of a rotor (50) of a wound-rotor synchronous machine (50) powered by a three-phase electric power network, comprising: - a step of injecting, into the three-phase electrical network, a high-frequency voltage signal; - a step (101) of demodulating the currents transformed by the second transformation step (101), comprising high-pass or band-pass filtering, and for determining an estimation error signal (ϵ); - a step of estimating (102) the phase shift (ϕcomp) produced by the rotor acceleration and by the high-pass or band-pass filtering of the demodulation step (101) to refine the estimation error signal (ε) determined during the demodulation step (101); a step (103) of separating the high-frequency component from the low frequency of the measured currents; the method further comprising a second part (12) for gradually estimating the position, speed and acceleration of the rotor, with gain parameters decoupled from each other, according to the sign of the obtained estimation error.
