摘要

The instability of the speed-sensorless induction motor (IM) drives based on an adaptive full-order observer in the regenerative region is well recognized. The stability of this system is depended on feedback gains of the adaptive full-order observer, therefore, the feedback gains design for a stable adaptive full-order observer and the practical design are essentially. In this paper, the practical and simple feedback gains design for a stable adaptive full-order observer is an introduced in wide operating regions. Moreover, the observers are satisfied by global and local stability. Validity of the designed sensorless control is confirmed by simulation and experiment.
