Observer-Based Method of Feature Extraction for the Fault Detection of Permanent Magnet Synchronous Motors

by Hoang Giang Vu and Thi Thuong Huyen Ma

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 942–948, 2021; DOI: 10.25046/aj0602107

Abstract:

This paper presents a new observer-based method which deals with the extraction of amplitude of characteristic frequencies for the fault diagnosis in permanent magnet synchronous motors (PMSM). First, a pilot survey is made to investigate the typical harmonics in the line currents of PMSM. Second, an appropriate structure of observer is formulated with the input…

Field Oriented Control and Commutation Based on Sensorless Methods for High-Speed Electrical Motors of Unmanned Multicopters

by Chen Zhao, Weisheng Kong, Federico Percacci and Patrik Gnos

Advances in Science, Technology and Engineering Systems Journal, Volume 7, Issue 6, Page # 58–69, 2022; DOI: 10.25046/aj070607

Abstract:

In recent years, unmanned aerial vehicles (UAVs), especially small and light multicopters driven by electrical motors and batteries, have experienced a boom in applications. The electrical drive system is a central component of these UAVs. This paper introduces the basics of these drives and presents control methods for them using permanent magnet synchronous motors (PMSMs).…
