On the Transition Improvement of EV or HEV Induction Motor Propulsion Sensor Fault-Tolerant Controller

Résumé

This technical paper deals with the transition performance improvement of a sensor fault-tolerant controller devoted to Electric (EV) or Hybrid Electric Vehicles (HEV). Indeed, improvements are brought over a previously developed technique that exhibit abrupt changes in the torque if a sensor fault is detected and after a transition from a control technique to another one [1]. The Fault-Tolerant Control (FTC) system firstly concerns the sliding mode control technique since better performances are obtained with an encoder to get the speed information. In the event of unavailability of the speed sensor, a sensorless fuzzy control technique is applied. In the proposed active fault-tolerant control approach a short and a smooth transition are achieved from the encoder-based control technique to the sensorless one using an appropriate fuzzy logic decision approach.
