TY - JOUR U1 - Wissenschaftlicher Artikel A1 - Wilcken, Nils A1 - Grotjahn, Martin T1 - Rotor Position Estimation for Permanent Magnet Synchronous Machines using Electromotive Force and Anisotropy Using Extended-Kalman-Filter JF - Forschung im Ingenieurwesen N2 - In this paper a new rotor position observer for permanent magnet synchronous machines (PMSM) based on an Extended-Kalman-Filter (EKF) is presented. With this method, just one single EKF is sufficent to evaluate the position information from electromotive force (EMF) and anisotropy. Thus, the PMSM can be controlled for the entire speed range without a position sensor and without the need to switch or synchronize between different observers. The approach covers online estimation of permanent magnetic field and mechanical load. The resulting EKF-based rotor position estimator is embedded in the existing cascaded control concept of the PMSM without need of additional angle trackers or signal filters. The experimental validation for the position sensorless control shows optimized dynamic behaviour.
