Cascade sliding mode controller for self-excited induction generator

This paper presents a simple control structure based on the sliding mode algorithm for an isolated-loaded induction generator (IG). The machine delivers an active power to a dc-load via a converter connected to a single capacitor on the dc side. Since the converter/capacitor model is nonlinear, the sliding mode technique constitutes a powerful tool to ensure the dc-bus voltage regulation. The computer simulations are provided to verify the validity of the proposed control algorithm. Resume - Ce papier presente une commande de structure simple basee sur l'algorithme du mode de glissement pour une generatrice asynchrone auto excitee. La generatrice delivre une puissance active a une charge continue par la voie d'un convertisseur connecte a un condensateur du cote continu. Puisque le modele convertisseur / condensateur est non lineaire, la technique du mode de glissement constitue un outil puissant pour assurer la regulation de la tension du bus continu. Les simulations par ordinateur sont fournies pour verifier la validite de l'algorithme du controle propose.
