Abstract

The subject of this paper is to stabilize sensorless vector control system of induction motors based on the adaptive observer in regenerating mode at very low speed. The adaptive observer gains are designed by Routh-Hurwitz criteria. It is verified that the proposed system is stable by the simulation and experiment.
