Survey on Fault-Tolerant Diagnosis and Control Systems Applied to Multi-motor Electric Vehicles

Abstract

Abstract. In the last years we have witnessed a growing interest, by the academic community and the automotive industry, in the multi-motor electric vehicles. The electrical nature of the propulsion is going to stress even more an increasing insertion of electronic devices in the vehicles. Furthermore, carmakers are performing research and already presented some vehicles based on the concept of X-By-Wire. Consequently, the growing complexity of the actuators and their control, as well as the need of increasing the safety and reliability of the vehicles obliges to the study and development of intelligent computational systems dedicated to the detection and diagnosis of failures in the electric propulsion. Hence, it is fundamental to start advanced studies leading to the development of innovative solutions that embed fault-tolerant electric propulsion in the electric vehicles. Accordingly, the main objective of this work consists on the bibliographic revision and study of fault-tolerant diagnosis and control systems dedicated to multi-motor electric vehicles.

A Survey of Fuzzy Algorithms Used in Multi-Motor Systems Control

“…This being the case, the authors propose a fault-tolerant controller based on sliding mode techniques. Further bibliographic review and study of fault-tolerant diagnosis and control systems for multi-motor electric vehicles can be found in [18]. The implementation of the electrical vehicle drive control algorithm with torque distribution on an FPGA platform is described in [19].…”

Proprioceptive Sensors’ Fault Tolerant Control Strategy for an Autonomous Vehicle

“…It is based on the inter-connection between the domains of system modelling, control theory and fault diagnosis. Several techniques and methodologies have been inventoried in review papers [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Mainly, there are two major branches of fault tolerant control, techniques that need a system analytical model and techniques that do not.…”

Fault-tolerant control based on sliding mode for overactuated electric vehicles

“…The technological breakthrough in electric vehicles and the implementation of multi-motor architecture in ground vehicles created an opportunity to explore the advantages of control in over actuated systems [1], [2]. The fast transient response of electric motors as well as the interesting torque/speed characteristic, gives an exciting lead over the combustion motors.…”
