Feldorientierte Regelung der Permanentmagnet-Synchronmaschine auf Basis des Drehzahlistwertes mit Winkelfehlerkorrektur

This paper describes a concept for the control of a permanent magnet synchronous machine. Calculating the rotor position by integration of the measured speed signal instead of using a position sensor is the significant feature of the concept. Due to dynamic and static deviations of the speed signal an accumulation of a position-error is unavoidable. A method is presented of how to recognize and correct such errors using the measured machine currents. The usability of the concept is shown by simulation-results and measurements from a laboratory test with a 7 kW machine.
