In this paper, a sensorless control scheme is presented for induction motors with core loss.
First, a controller is designed using a high order sliding mode twisting algorithm, to track a …

The design of observers for nonlinear systems with unknown, time-varying, bounded delays,
on both state and input, still constitutes an open problem. In this technical note, we show …

This article first shows that the advanced high-gain adaptive observer (AO) is able to
estimate both speed and resistances during speed transients. However, it is also found that …

A new technique to observe the electromagnetic torque of a permanent magnet
synchronous machine based on flux linkage estimation considering unknown magnetic …

This paper introduces a fuzzy virtual reference model (FVRM) synthesis method for linear
induction motor (LIM) speed sensorless tracking control. First, we represent the LIM as a …

One of the main challenging issues in induction motor drives is the lack of knowledge about
the actual values of some critical parameters, such as rotor and stator resistances which are …

In this paper, a sensorless fault tolerant controller for induction motors is developed. In the
proposed approach, a robust controller based on backstepping strategy is designed in order …

In this paper, a second order sliding mode observer for the induction motor without
mechanical sensor is presented. This observer converges in finite time and is robust to the …

It is known that the reconstructed phase portrait of a given system strongly depends on the
choice of the observable. In particular, the ability to obtain a global model from a time series …

This paper addresses the problem of accurately estimating the mechanical and magnetic
state variables as well as the stator and rotor resistances of induction motors using only the …
