Abstract

This paper proposes a structural fault recoverability analysis using the bond graph (BG) approach. Indeed, this tool enables structural analysis for diagnosis and fault tolerant control (FTC). For the FTC, we propose an approach based on the inverse control using the inverse BG. The fault tolerant control method is also compared with another approach. Finally, simulation results are presented to show the performance of the proposed approach.

Highlights

Due to the growing complexity of the dynamical systems, there is an increasing demand for safe operation, fault diagnosis (FDI), and fault tolerant control (FTC)
FTC is categorized into two different techniques: passive FTC (PFTC) [6, 7] and active FTC (AFTC) [8, 9]
In the first part of the paper, we propose a methodology based on bond graph (BG) model for fault detection and fault tolerant control

Summary

Introduction

Due to the growing complexity of the dynamical systems, there is an increasing demand for safe operation, fault diagnosis (FDI) (fault detection and isolation), and fault tolerant control (FTC) (strategies for control redesign). Different approaches have been developed for the designing and the implementation of FDI and FTC procedures [1]. These techniques are based on the knowledge of the system model (model-based methods) [2, 3] or its structure (databased methods) [4, 5]. FTC is categorized into two different techniques: passive FTC (PFTC) [6, 7] and active FTC (AFTC) [8, 9]. The AFTC approach reacts to system component failures actively by reconfiguring control actions and acceptable performance of the entire system can be maintained
