“…Thanks to this modelling method, terminals are created on the model. Then no modification is required when tests are to be performed contrary to traditional models which integrate an inside load [13], [18], [1], [19]. The generator's terminals are connected to one bloc containing the nominal load and a potential fault.…”

The paper mainly deals with the synchronous generator output voltage control by using a non linear control strategy: the sliding mode. The originality is not only due to the involved control strategy but also the use of a voltage source for the machine's excitation and thyristors bridge. The favourable arguments to the sliding mode control are decoupling design procedure and easy implementation by power converters. The system stability is ensured by using a Lyapunov function. Thanks to the new excitation system based on voltage source, the system's dynamics is improved in spite of the chattering phenomena induced by the sliding mode control. Simulations are done with Matlab/Simulink T M and a discussion on the results is exposed at the end of the paper.

“…A number of rotor windings suitable for accounting for skin effects could also be chosen to enhance the accuracy of the model. It is established in [5] that the equation of an accurate induction-machine model, including the neutral connection for both symmetrical and asymmetrical test analysis, can be described by the following (1)-(5):…”

The paper describes an effective formulation of a maximum-likelihood identification algorithm for linear estimation of the equivalent-circuit parameters of cage-type (single cage and double cage) or deep-bar induction motors with measurement and process noises. A complete generalized model for symmetrical and asymmetrical test analysis of induction machines is developed for this purpose. The paper outlines the theory and reasoning behind the proposed statistical-based treatment of online data derived from generalized least-squares estimator and a Kalman filter. The method is successfully applied to online double-line independent finite-element (FE) short-circuit-simulated records of a deep-bar-type induction motor.

“…In the last decades, coupled field-circuit models of rotating electrical machinery have received much attention from both academia and the industry [11][12][13][14][15]. Among the techniques available to manage coupled field-circuit formulations of electrical machines in practice, the finite element method (FEM) has emerged as the dominating method [16].…”
