应用自抗扰控制的车辆制动力优化分配策略
Vehicle braking force optimization with active disturbance rejection control allocation strategy
摘要
Abstract
In light of research aimed at improving safety during braking at curves,this paper presents a novel brake force optimization control strategy to enhance vehicle handling safety.An ADRC(adaptive robust control)controller based on yaw rate control is designed to calculate the required additional yaw moment.An optimization algorithm is then employed to solve the necessary brake force at each wheel.A co-simulation is conducted using CarSim/Simulink,and the proposed strategy is compared with a fixed brake force distribution strategy.The simulation results indicate the ADRC controller's brake force optimization strategy enables the vehicle to effectively follow the yaw rate during emergency braking in curves at 90 km/h and a braking intensity of z=0.7,thereby preventing vehicle instability.When the braking intensity is z=0.3,the maximum deviation of the yaw rate is reduced by 0.043 67 rad/s,and the maximum deviation of the side slip angle is down by 0.582 46°,markedly improving the vehicle's handling stability.关键词
