摘要
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。
Delays between speed changes of a lead vehicle and a following vehicle controlled by an automatic cruise control system often cause the cruise control to make rapid changes in the vehicles speed. A vehicle speed and vehicle to vehicle distance control algorithm for stop-go cruise control system was developed using a control factor and a cost function to provide optimum control. The cost function is used to analyze the relationship between the control factor value and the controller performance. Theoretical analysis and simulation results show that the controller reduces the delay between speed changes and responds to changes in the vehicle mass.
