Abstract :
Speed-Sensorless control schemes for AC-Drives are today standard features in industrial drives. Yet the quality of the implemented systems is different depending mainly on how precise the AC-machine is modeled and on the accuracy of the parameters. The present paper introduces an online adaption of the parameters of the PMSM based on the fundamental machine model during normal operation. The performed investigations confirm the proposed method to be suitable for servo-drive systems with high dynamics but also point out its limits.
