Abstract
A simple position-sensorless method for the rotor-side
field-oriented control of a wound-rotor induction machine is described
in this paper. The algorithm is based on axis transformations. Compared
to the previously proposed methods, it is more direct and the dependence
on machine parameters is also largely reduced. The algorithm can be
started on the fly without the knowledge of the initial rotor position.
Operation at synchronous speed, corresponding to zero rotor frequency,
is stable, thus making it suitable for variable speed constant frequency
operations. Simulation and experimental results show excellent
performance of the scheme
