基于故障诊断的分布式电动汽车容错控制策略
Fault-tolerant Control Strategy for Distributed Electric Vehicles Based on Fault Diagnosis
摘要
Abstract
In view of the safety risk brought by motor failure in the driving process of distributed elec-tric vehicles,a fault-tolerant control strategy based on motor failure diagnosis and sliding mode control was proposed,and a vehicle controller was designed.The controller adopted a two-layer structure.The upper controller was the calculation module for driving torque and additional yaw moment,while the lower controller was a fault-tolerant control module.Based on TruckSim software,a model of distribut-ed electric vehicles was established,and the simulation of sinusoidal input and double-line-change in-put conditions under single-motor failure mode was carried out.The experimental results show that the fault-tolerant controller can accurately identify the fault and correctly redistribute the driving torque,and the torque response is fast.关键词
