针对单一设计距离控制中出现的速度滞后问题,综合考虑速度和距离的控制,提出了一种基于“起停”巡航控制系统的纵向车间距控制器设计方法。该控制器的设计中引入了控制因子,建立了兼顾速度和距离控制的目标性能函数,并对控制因子的取值作了讨论。通过理论分析和仿真实验表明,所提出的控制方法使速度滞后的问题得到改善,同时控制器对质量具有鲁棒性。
Aiming at the speed lag problem in the single design distance control, considering the control of speed and distance, a design method of longitudinal distance controller based on the “start / stop” cruise control system is proposed. The control factor is introduced in the design of the controller, and a target performance function that takes both speed and distance control into account is established. The control factor is discussed. The theoretical analysis and simulation results show that the proposed control method improves the speed lag problem and the controller is robust to quality.
