Abstract :
In this paper a nonlinear model for AC machines is proposed that takes into account the magnetic saturation and magnetic interaction between both orthogonal magnetic axes. Furthermore, the model includes the presence of air-gap flux harmonic components caused by magnetic saturation and multiple-pole spatial saliencies. Such a model is used to describe in a uniform way motion-state estimators for AC drives that are recently discussed in the literature. Emphasis is given to salient-pole synchronous machines with a rotor field winding or a permanent-magnet excitation (PMSM)
