Global observability analysis of sensorless induction motors
The authors perform an observability analysis of an unsaturated induction motor model without sensors. The set of indistiguishable trajectories is characterized by the solutions of a system of differential algebraic equations and equivalently of a system of differential equations on a manifold. These characterizations are used in order to give conditions for observability and the existence of observers.
