DSP-based sensor fault detection and post fault-tolerant control of an induction motor-based electric vehicle

Abstract

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 fault-tolerant control to allow the vehicle continuous operation. The proposed approach is validated through experiments on an induction motor drive and simulations on an electric vehicle using a European urban and extraurban driving cycle. © 2012 Bekheïra Tabbache et al.
