摘要
设计了二层式结构的Stop & Go巡航控制器,上层控制器采用LQ最优算法得出期望的加速度,下层控制器采用PI算法,实现对期望加速度的跟踪.多种工况下的仿真与实车试验表明,控制器能合理控制车辆起步、加速、停车,有较强的抗干扰性,控制过程平稳.
A Stop & Go cruise controller with a two-layer structure is designed in the paper. The upper controller based on LQ algorithm was adopted to obtain the desired acceleration. Conventional PI algorithm was used to design the lower layer controller to obtain the desired acceleration. Experiment shows that this controller with good anti-interference effect cart control vehicle start, acceleration and stop reasonably, and the control process is stable.
