This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...

Speed‐Sensorless Model‐Free Predictive Torque Control for Induction Motor Drive
A speed‐sensorless MF‐PTC based on EKF is proposed for a 2L‐VSI‐fed IM drive to reduce the overall cost and complexity of the drive system. The rotor speed is estimated using the EKF. The instant rotor flux is also estimated using the EKF based on the rotor current model of IM, whereas a direct machine model is employed in general to estimate the rotor

Sensorless control of deep-sea ROVs PMSMs excited by matrix converters [PDF]
The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control

Observers Design For Sensorless PMSMs
A state observer is proposed for permanent magnet synchronous motors (PMSMs). The gain of this observer involves a design function that has to satisfy some mild conditions which are given. Different expressions of such a function are proposed. Of particular interest, it is shown that high gain observers and sliding mode like observers can be derived by

The position measurement angle error (contains measurement delay angle and periodic angle error) plays a significant role in PMSM drives, especially when the motor is rotating in the flux weakening (FW) region. In this paper, the impact of the position angle error on the performance of the PMSM drives for EPS in a wide speed range has been elaborated ...
