摘　　要：为提高车辆的主动安全性和操纵稳定性,在介绍汽车稳定性控制系统分层体系结构的基础上,针对汽车侧向、横摆及侧倾动力学的耦合问题,提出了一种采用线性矩阵不等式方法的横摆与侧倾稳定的最优鲁棒控制策略,通过差动制动与主动悬架系统实现了横摆稳定与侧翻预防功能.并在CarSim与Matlab/Simulink环境下进行了仿真试验,结果表明横摆与侧倾最优控制策略对车辆横摆稳定性控制具有良好的作用.In order to enhance vehicle active safety and manoeuvrability,a hierarchical architec- ture is introduced for the vehicle electronic stability control system. Considering the counpling of lateral, yaw and roll dynamics ,an optimal robust control strategy is proposed based on linear matrix inequality method. The yaw moment for a differential braking system is simultaneously optimized as well as the roll moment for a active suspension system to enhance the yaw stability and rollover pre- vention. The performance of the proposed control algorithms is verified with results of the co-simulation with CarSim and Matlab/Simulink.
