Fault Diagnosis Methods and Fault Tolerant Control Strategies for the Electric Vehicle Powertrains

Residual Generator Selection for Fault Diagnosis of Hybrid Vehicle Powertrains

The performance of a model based diagnosis system is affected by the selection of consistency relation in a set of equations with analytical redundancy in a non-linear system. To investigate aspects due to this, two diagnosis systems of a parallel hybrid truck are designed, and both static and dynamic issues are considered. A simplified vehicle model is used to exemplify how a unique expression...

Fault Diagnosis and Fault-tolerant Control

New Strategies for Fault Tolerant Control and Fault Diagnostic

A recent architecture based on the Youla parameterization is analyzed for the nominal and uncertain case. This special architecture is characterized by a separation principle for the controller. In this paper, several stability results that allow to extend the structure to the integrated control/filter approach are presented. Two algorithms based on the recursive design and nesting of the integ...

DSP-Based Sensor Fault Detection and Post Fault-Tolerant Control of an InductionMotor-Based Electric Vehicle

This paper deals with sensor fault detection within a reconfigurable direct torque control of an induction motor-based electric vehicle. The proposed strategy concerns current, voltage, and speed sensors faults that are detected and followed by post faulttolerant control to allow the vehicle continuous operation. The proposed approach is validated through experiments on an induction motor drive...

Fault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault

In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...
