Induction machines have recently been very popular in variable-speed drives, because of
their robust construction and relatively low manufacturing costs (brushless), maintenance …

After a technical review on the stator resistance and rotor resistance identification methods
for speed sensorless induction motor drives, this paper presents a different solution with a …

This article uses the active flux concept to review fundamental frequency sensorless
algorithms for both induction and permanent magnet motors in one framework …

In this paper, a new model reference adaptive controller (MRAC) for the speed estimation of
the vector-controlled induction motor drive is presented. The proposed MRAC is formed …

In this work, we investigate the adaptive sliding-mode observer design problem for the
selective catalytic reduction (SCR) system in diesel-engine aftertreatment systems. First, an …

In this article, a new design of the state observer is proposed to reduce the unstable low-
speed region of the adaptive full-order observer (AFO) based speed sensorless speed …

This paper addresses the problem of stator and rotor resistances identification in speed
sensorless induction motor (IM) drives. The IM model that is transformable into the adaptive …

This paper presents an analysis by which the stability of a multiple-input-multiple-output
system of simultaneous speed and stator resistance estimators for sensorless induction …

Parameter mismatches seriously impact the stability and the rotor-speed accuracy in
sensorless induction motor drives, particularly in low speed. To deal with the parameter …

In this article, the stability problem of the stator current error-based model reference adaptive
system (MRAS) speed estimator for induction motor drive is discussed. The MRAS CC that is …
