电驱动汽车横摆稳定性自适应积分终端滑模控制
Adaptive integral terminal sliding mode control for transverse yaw stability of electric vehicles
摘要
Abstract
To improve the yaw stability of a distributed-drive electric vehicle,we design a direct yaw control strategy based on adaptive integral terminal sliding mode control through a hierarchical control approach.The upper level of the control strategy is designed as an adaptive integral terminal sliding-mode controller to compute the target additional cross-swing torque.The lower level of the control strategy,with the optimization objective of minimizing the tire adhesion utilization,is designed by employing a quadratic programming control algorithm to create an optimized torque distribution controller.The effectiveness of the controller is simulated and verified by Matlab-CarSim co-simulation.Our results show under the high adhesion coefficient road surface,the peak center of mass lateral deflection of the vehicle with adaptive integral terminal sliding mode controller decreases by 17.1%and 1.7%,and the peak sway angular velocity is down by 13.7%and 3.4%compared with those of the uncontrolled and integral sliding modecontrolled vehicles.Under low adhesion coefficient road surface,the peak center of mass lateral deflection decreases by 69%and 39.4%and the peak sway angular velocity is down by 16%and 2.4%compared with those of the uncontrolled and integral sliding mode controlled vehicles,improving the electric vehicles'stability and driving safety.关键词
