Abstract| Conditions for observability of a linearized smoothairgap induction machine model are examined, and limitations of any speed-sensorless observer scheme based on such a model are discussed. An approach for speed-sensorless ux estimation based on two-time-scale theory is developed. This approach relies on the natural time-scale separation between the electrical and mechanical dynamics of the induction machine. A full-order observer of an induction machine is presented, incorporating adoi:10.1109/ias.1996.557016 fatcat:jx2iqkfgbnat3g5b3aklflzkli
