About this book

This thesis reports on novel methods for gain-scheduling and fault tolerant control (FTC). It begins by analyzing the connection between the linear parameter varying (LPV) and Takagi-Sugeno (TS) paradigms. This is then followed by a detailed description of the design of robust and shifting state-feedback controllers for these systems. Furthermore, it presents two approaches to fault-tolerant control: the first is based on a robust polytopic controller design, while the second involves a reconfiguration of the reference model and the addition of virtual actuators into the loop. Inaddition the thesis offers a thorough review of the state-of-the art in gain scheduling and fault-tolerant control, with a special emphasis on LPV and TS systems.

Chapter 1. Introduction
Abstract
The results presented in this thesis have been developed at the Research Center for Supervision, Safety and Automatic Control (CS2AC) of the Universitat Politècnica de Catalunya (UPC) in Terrassa, Spain. The research was jointly supervised by Dr. Fatiha Nejjari and Dr. Vicenç Puig, and was sponsored partly by UPC through an FPI-UPC grant and by the Agència de Gestió d’Ajuts Universitaris i de Recerca (AGAUR) through contracts FI-DGR. The supports are gratefully acknowledged.

Chapter 6. Background on Fault Tolerant Control
Abstract
Fault tolerant control (FTC) is the name given to all those techniques that are capable of maintaining the overall system stability and acceptable performance in the presence of faults. In other words, a closed-loop system which can tolerate component malfunctions, while maintaining desirable performance and stability properties is said to be a fault tolerant control system (FTCS). Starting from the 80s, FTC applications began to appear in the scientific literature, mainly motivated by aircraft flight control system designs.
