Contents The problem of observer design naturally arises in a system approach, as soon as
one needs some internal information from external (directly available) measurements. In …

Thanks to the technology developments and the recent advances in control theory, it is
possible to implement new controllers to a large number of Alternative Current (AC) …

This paper deals with the observability analysis and the observer synthesis of a class of
nonlinear systems. In the single output case, it is known [4–6] that systems which are …

This paper addresses the problem of controlling wind energy conversion (WEC) systems
involving permanent magnet synchronous generator (PMSG) fed by IGBT-based buck-to …

An efficient sensor-less speed estimator, based on an adaptive non-linear high gain
observer (HGO) which uses only the measured stator currents and control voltages in the …

In this paper, a sensorless speed control for interior permanent magnet synchronous motors
(IPMSM) is designed by combining a robust backstepping controller with integral actions …

In this paper a robust sensorless control for an Interior Permanent Magnet Synchronous
Motor (IPMSM) is designed. The proposed control strategy uses a backstepping controller …

On the basis of high-gain observers for perturbed state affine systems, an observer for a
class of nonlinear systems satisfying a more general triangular structure is proposed. The …

In this paper, an observer-based controller scheme is designed to robustly drive a
sensorless Induction Motor (IM) even for the case of low frequencies with unknown load …

Ce travail s' inscrit principalement dans le domaine de l'observation et de la commande non
linéaires pour la machine asynchrone sans capteurs mécaniques. La première partie est …
