Approche géométrique de la modélisation des machines électriques en vue de l'observation et de la commande

Abstract : The study is presented in the context of reducing adverse electrical and mechanical systems related to industrial change in speed of rotating electrical machines. Based on a Tensor dedicated to the study of electrical machines, we developed a model taking into account the geometric imperfections of origin, the latter resulting in harmonic space. Each harmonic is then regarded as essential to a virtual machine, based on the principle of superposition. The model is thus made up of as many virtual machines as harmonics. The study of a model point of view is then automatically performed. Finally, an observer state Kalman type associated with this model is developed. The case of a model for a harmonic space is processed and the validation of the observer is performed on an asynchronous motor with rotor windings. The current estimate is measured for experimental validation.
