Fault diagnosis for Takagi-Sugeno nonlinear systems

Fault Tolerant Control Design For Takagi-Sugeno Nonlinear Systems

In this paper, a new actuator fault tolerant control strategy is proposed for nonlinear Takagi-Sugeno systems. The proposed control law uses the estimated fault and the error between the faulty system state and a reference system state. A proportional integral observer with unknown inputs is conceived in order to estimate simultaneously states and actuator faults. The problem of design of obser...

New fault tolerant control strategies for nonlinear Takagi-Sugeno systems

New methodologies for Fault Tolerant Control (FTC) are proposed in order to compensate actuator faults in nonlinear systems. These approaches are based on the representation of the nonlinear system by a Takagi–Sugeno model. Two control laws are proposed requiring simultaneous estimation of the system states and of the occurring actuator faults. The first approach concerns the stabilization prob...

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

Predictive and robust fault-tolerant control for Takagi-Sugeno systems

The paper deals with the problem of robust predictive fault-tolerant control for nonlinear discrete-time systems described by the Takagi-Sugeno models. The proposed approach consists of three steps, i.e. it starts from fault estimation, the fault is compensated with a robust controller, and finally, when the compensation is not successful then a suitable predictive action is performed. This app...

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...
