摘要
使用自抗扰控制(active disturbance rejection control,ADRC)方法对车辆纵向加速度控制进行研究.首先给出以油门开度指令为控制量的发动机动态模型和车辆纵向动力学模型,对ADRC进行简要介绍;然后将模型变换为适于自抗扰控制的仿射系统,设计车辆纵向加速度ADRC控制器;最后在车辆和发动机参数摄动以及道路扰动的环境下进行仿真.结果表明,ADRC控制器能够使车辆获得快速、平稳和高精度的加速度控制效果.
The active disturbance rejection control （ADRC） method was utilized to study vehicle longitudinal acceleration control. First the dynamic vehicle longitudinal locomotion model and the dynamic engine model were given, which can use the throttle open angle command as input and the traction force as output. The ADRC was briefly introduced. Then the models were trans- formed to an afl^ned model, and the ADRC controller was designed. Finally, simulations were done under vehicle and engine＇ parameters perturbations and road disturbance conditions. The results show that the ADRC controller can make the vehicle accomplish a speedy, smooth and high precision acceleration control effect.
