Imitation Modeling of an Inter-Turn Short Circuit of an Asynchronous Motor Stator Winding for Diagnostics of Auxiliary Electric Drives of Transport Infrastructure

Communications, 2021
A scientific approach to calculating the parameters and characteristics of an asynchronous motor in the inter-turn short circuit mode in one phase of the stator is proposed to create the foundations of a diagnostic complex for assessing the condition of ...

Backstepping Control Based on a Third-order Sliding Mode Controller to Regulate the Torque and Flux of Asynchronous Motor Drive

Periodica Polytechnica Electrical Engineering and Computer Science, 2022
This work represents a new nonlinear control for the asynchronous motor (AM) drive. The designed nonlinear control is based on the combination between the backstepping control (BC) scheme and third-order sliding mod control (TOSMC).

Optimization of PI Controller Parameters by GWO Algorithm for Five-Phase Asynchronous Motor

Energies, 2023
Operation at low speed and high torque can lead to the generation of strong ripples in the speed, which can deteriorate the system. To reduce the speed oscillations when operating a five-phase asynchronous motor at low speed, in this article, we propose ...

Motor Imagery Classification for Asynchronous EEG-Based Brain–Computer Interfaces [PDF]

IEEE transactions on neural systems and rehabilitation engineering
Motor imagery (MI) based brain-computer interfaces (BCIs) enable the direct control of external devices through the imagined movements of various body parts. Unlike previous systems that used fixed-length EEG trials for MI decoding, asynchronous BCIs aim

Vector Control of Asynchronous Motor of Drive Train Using Speed Controller H∞

Emerging Science Journal, 2022
This study proposes the speed control of an asynchronous motor (AM) using the Antiwindup design. First, the conventional vector control based on proportional-integral (PI) controllers is developed for a constant speed set point.

Equivalent Inertia Estimation of Asynchronous Motor and Its Effect on Power System Frequency Response

Energies, 2022
With the increase in renewable energy penetration, the traditional synchronous generator is gradually replaced, resulting in the decrease in system inertia level and the weakening of frequency modulation capability.
