1. Reducing the Effects of Inaccurate Fault Estimation in Spacecraft Stabilization
ABSTRACT Reference Governor is an important component of Active Fault Tolerant Control. One of the main reasons for using Reference Governor is to adjust/modify the reference trajectories to maintain the stability of the post-fault system, especially when a series of actuator faults occur and the faulty system can not retain the pre-fault performance. Fault

2. MONITORING THE STATOR CURRENT IN INDUCTION MACHINES FOR POSSIBLE FAULT DETECTION: A FUZZY/BAYESIAN APPROACH FOR THE PROBLEM OF TIME SERIES MULTIPLE CHANGE POINT DETECTION
ABSTRACT This paper addresses the problem of fault detection in stator winding of induction machine by a multiple change points detection approach in time series. To handle this problem a new fuzzy/Bayesian approach is proposed which differs from previous approaches since it does not require prior information as: the number of change points or the characteri

3. Design of a multi-model observer-based estimator for Fault Detection and Isolation (FDI) strategy: application to a chemical reactor
This study presents a FDI strategy for nonlinear dynamic systems. It shows a methodology of tackling the fault detection and isolation issue by combining a technique based on the residuals signal and a technique using the multiple Kalman filters. The usefulness of this combination is the on-line implementation of the set of models, which represents the norma

4. Algoritmo de detecção de falhas para sistemas telefonicos utilizando a teoria do perigo / Fault detection algorithm for telephone systems using the danger theory
Abstract This thesis presents a fault detection algorithm composed of multiple interconnected modules, and operating according to the paradigm supported by the Danger Theory in immunology. This algorithm attempts to achieve significant features that a fault detection system is supposed to express when monitoring a telephone system. These features would basic
