| Abstract |
This paper presents a robust observer based on redundancy computing emf on 2 axis rotor oriented reference frame. the first step is a stalling phase avoiding any wrong rotation whatever the rotor initial position is. The second step is a calibration phase, to estimate accurately the electrical parametres of the drive. Using the first two steps, we finally control the sensorless drive by estimating emf, velocity and position which are quite close to reality only by voltage and current measurements. |
