Abstract

This paper presents a robust observer based on redundancy computing EMF on 2-axis rotor oriented reference frame. Driving sensorless synchronous machine is presented in 3 steps. The first is a stalling phase to avoid wrong rotation whatever the initial rotor position is. The second step is a calibration phase, to estimate accurately the electrical parameters of the drive. So using the 2 first step, finally we control the sensorless drive by estimating EMF, velocity and position which are quite close to reality only by voltages and currents measurements.
