基于L MI的汽车主动悬架防侧翻 H∞控制

摘要

提出了一种基于主动悬架的 H∞控制策略。在 Matlab/Simulink 环境下进行了仿真计算，仿真结果表明：采用所提出的 H∞控制策略，可以有效地降低汽车非直线行驶时的侧倾角以及侧倾角速度，提高汽车的侧翻稳定性，降低汽车侧翻事故发生可能性。%H control strategy is proposed based on active suspensions for vehicle.Under the Mat-lab/Simulink,the simulation is done and the re-sults show that the presented control scheme not only can reduce the roll angle and roll angular ve-locity,but also can improve the rollover stability of the vehicle and reduce the possibility of vehicle rollover accident.
