  1. 1. Control of permanent-magnet synchronous machines in automotive applications

    Author : Oskar Wallmark; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-wheel motor; sensorless control; electric vehicle; permanent-magnet synchronous machine; loss minimization; inverter; Electric drive; position estimation; vector control; hybrid electric vehicle; phase-locked loop; fault tolerance;

    Abstract : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotiveapplications.Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly.
