摘　　要：针对受约束网联车队受到加速度拒绝服务(DoS)攻击的情况,提出一种新的安全协同自适应预测巡航控制算法。首先,结合运动学特征设计加速度估计器以缓解DoS攻击对巡航控制器的影响,再设计特定的综合轨迹信号以灵活表示网联车队的各种交通工况。其次,采用滚动时域优化原理和分布式模型预测控制(MPC)框架,提出满足安全约束的车辆队列安全协同自适应预测巡航控制策略。在此基础上,采用线性矩阵不等式方法,给出在安全约束和加速度DoS攻击下的队列稳定性和弦稳定性的充分条件。最后,通过典型交通场景仿真验证本文算法的有效性。A new security-oriented cooperative adaptive predictive cruise control(CAPCC)algorithm is presented for connected and automated vehicle(CAV)platoons subject to constraints and Denial of Service(DoS)attacks of predecessors'acceleration.Firstly,using the kinematic characteristics,the acceleration estimator is designed to alleviate the effect of DoS attacks on cruise controllers.Then the synthetical trajectory signals are designed to flexibly represent various traffic situations of CAV platoons.Secondly,by adopting the receding horizon optimization principle,the secure CAPCC scheme of the vehicle platoon with satisfactions of the safety constraints is formulated in the framework of distributed model predictive control.Moreover,some sufficient conditions in the form of linear matrix inequalities are obtained to ensure stability and string stability of the platoon in the presence of safety constraints and the acceleration DoS attacks.Finally,some simulation experiments in representative traffic scenarios verify the effectiveness of the presented algorithm.
