Yaw Stability Control of Distributed Drive Electric Vehicle Based on Multi-Objective Parallel Chaos Optimization
摘要
Abstract
Yaw stability is an important problem in the stability study of distributed drive electric vehicles(DDEV).In order to solve the problems of complex structure and strong coupling in yaw stability,a control system based on multi-ob-jective parallel chaos optimization is proposed for DDEV in this paper.This control system consists of two parts.The upper controller employs a multi-objective optimization strategy,leveraging a multi-objective parallel chaotic optimization algo-rithm,to determine the optimal yaw rate and desired slip rate essential for maintaining lateral stability in a distributed drive electric vehicle.The lower controller is execution unit,two fuzzy logic controllers are adopted to correct front wheel steer-ing angle and distribute drive/brake torque respectively,according to the optimal desired variables computed by the upper controller.The modeling and simulation process is completed on the Matlab/Simulink platform,and the results show that the control system optimally coordinates the active steering angle of the front wheels and the driving/braking torque to en-sure the lateral stability of the DDEV.关键词
