On the Control of the Permanent Magnet Synchronous Motor: An Active Disturbance Rejection Control Approach
Hebertt Sira-Ramírez,Jesus Linares-Flores,Carlos Garcia-Rodriguez,Marco Antonio Contreras-Ordaz +3 more
TL;DR: The proposed high-gain GPI observer-based ADR controller is justified in terms of a singular perturbation approach and verified by means of realistic computer simulations, using the MATLAB/SIMULINK-PSIM package.

Hidden oscillations in mathematical model of drilling system actuated by induction motor with a wound rotor
TL;DR: In this article, Mihajlovic et al. investigated the effect of hidden oscillations in a two-mass mathematical model of a drilling system and showed that these effects may lead to drill string failures and breakdowns.

An Adaptive Interconnected Observer for Sensorless Control of PM Synchronous Motors With Online Parameter Identification
TL;DR: Experimental results are shown to confirm the effectiveness of the proposed method and the convergence of the observer estimation error, and sufficient conditions are given to prove the practical stability.
Journal ArticleDOI
Estimation of Rotor Position and Speed of Permanent Magnet Synchronous Motors With Guaranteed Stability
TL;DR: Solutions to both problems, which are particularly tailored for the widely popular permanent magnet synchronous motors, are provided and Simulation and experimental results of the position observer, used together with a classical field-oriented control algorithm, are presented.

On Sensorless Induction Motor Drives: Sliding-Mode Observer and Output Feedback Controller
Malek Ghanes,Gang Zheng +1 more
TL;DR: A new sliding- mode observer that uses only the measured stator currents is synthesized to estimate the speed, flux, and load torque and a current-based field-oriented sliding-mode control is developed so as to steer the estimated speed and flux magnitude to the desired references.
