Fault-Tolerant Control of Permanent Magnet Synchronous Motor Drive under Open-Phase Fault

by Amr Saleh, Nada Sayed, Ghada Ahmed Abdel and Mona Nagieb Eskander

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 455–463, 2020; DOI: 10.25046/aj050654

Abstract:

This paper presents an integrated solution for a fault-tolerant three-phase permanent magnet synchronous motor (PMSM) field-oriented control drive subjected to an open-phase fault (OPF) integrated with effective fault-tolerant detection methodology. The fault detection methodology is based on model predictive current control (MPCC), which is easy to apply, detect OPF in a range of microseconds, and…

Robust Static Output-Feedback Fault Tolerant Control for a Class of T-S Fuzzy Systems using Adaptive Sliding Mode Observer Approach

by Slim Dhahri and Essia Ben Alaia

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 4, Page # 70–80, 2020; DOI: 10.25046/aj050410

Abstract:

In this paper, the problems of actuator and sensor fault estimation (FE) and fault-tolerant control (FTC) for uncertain nonlinear systems represented by Takagi-Sugeno (T-S) fuzzy models are investigated. First, a robust fuzzy adaptive sliding mode observer (SMO) is designed to simultaneously estimate system states and both actuator and sensor faults. Then, using the obtained on-line…
