针对通信网络影响下智能车队纵向控制这一重要课题,研究了车队控制系统反馈信息中部分信息存在丢包问题下的车队控制问题.建立了结合网络丢包因素的车队纵向动态模型,进一步完善了原有车队控制系统模型.在该模型的基础上设计动态输出异质反馈控制器,得到了保证车队系统均方稳定的条件,并进一步设计克服领队车辆以及外界风速等干扰的H∞控制器.仿真试验表明,本文获得的控制方法不但可实现车队的稳定运行控制,而且使车队控制效果大大改善.%The important issue of intelligent platoon longitudinal control via wireless communication network is studied in this paper. A model is established for the platoon's longitudinal movement.where the packets dropout are given considerations. A dynamic output hierarchical feedback control method is presented to overcome the effects of packets dropout. Moreover, to overcome the effect of the leader vehicle and wind gust disturbance,an H∞ controller design method is derived. Under this controller, the platoon can be stable. Simulation results are given to show the efficiency of the proposed results.
