Active Fault Tolerant Control (FTC) Design for Takagi-Sugeno Fuzzy Systems with Weighting Functions Depending on the FTC

Robust Fault Tolerant Control Framework using Uncertain Takagi-Sugeno Fuzzy Models

This chapter is concerned with the introduction of a fault tolerant control (FTC) framework using uncertain Takagi-Sugeno (FS) fuzzy models. Depending on how much information is available about the fault, the framework gives rise to passive FTC, active FTC without controller reconfiguration and active FTC with controller reconfiguration. The design is performed using a Linear Matrix Inequality ...

A fault-tolerant control strategy for Takagi-Sugeno fuzzy systems

Abstract: In this paper, a new active FTC strategy is proposed. First, it is developed in the context of linear systems and then it is extended to Takagi-Sugeno fuzzy systems. The key contribution of the proposed approach is an integrated FTC design procedure of the fault identification and fault-tolerant control schemes. Fault identification is based on the use of an observer. While, the FTC c...

Fault Tolerant Control for Nonlinear Systems Described by Takagi-sugeno Models

ABSTRACT: In this paper the problem of active fault tolerant control (FTC) in noisy systems is studied. The proposed FTC strategy is based on the known of the fault estimate and the error between the faulty system state and a reference system state. A proportional integral observer is used in order to estimate the state and the actuator faults. The obtained results are then extended to nonlinea...

Integrating Fuzzy based Fault diagnosis with Constrained Model Predictive Control for Industrial Applications

An active Fault Tolerant Model Predictive Control (FTMPC) using Fuzzy scheduler is developed. Fault tolerant Control (FTC) system stages are broadly classified into two namely Fault Detection and Isolation (FDI) and fault accommodation. Basically, the faults are identified by means of state estimation techniques. Then using the decision based approach it is isolated. This is usually performed u...
