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…

Real Time Implementation of an Improved Hybrid Fuzzy Sliding Mode Observer Estimator

by Sorin Mihai Radu, Elena-Roxana Tudoroiu, Wilhelm Kecs, Nicolae Ilias and Nicolae Tudoroiu

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 1, Page # 214–226, 2017; DOI: 10.25046/aj020126

Abstract:

This paper extends some of our research results disseminated in the most recent awarded international conference paper concerning the implementation in real time of a sliding mode observer state estimator. For the same case study developed in the conference paper, more precisely a DC servomotor angular speed control system, we extend the proposed concept of…
