摘要
建立了包含转向运动模型、俯仰运动模型和侧倾运动模型的汽车整车模型,在设计了电动助力转向系统PD控制的基础上,构建了基于自适应模糊控制的汽车主动悬架与电动助力转向系统集成控制器,当控制系统偏差变小或变大时,调整因子总能保证系统稳定,便于工程应用。计算结果表明,该自适应模糊集成控制策略,既保证了车辆操纵轻便性,又显著提高了整车操纵稳定性、安全性和行驶平顺性等整车综合性能。
A complete vehicle model containing steering model, pitch model and roll model is established. On the base of PD control for electric power steering system designed, an integrated controller for both active suspension system and electric power steering system of vehicle is constructed based on adaptive fuzzy Control. No mat- ter the deviation of control system become larger or smaller, the adjusting factor can always ensure the stability of the system. The calculated results show that the presented control scheme not only assures the maneuverability of vehicle, but also markedly enhance the handling stability, safety and ride comfort of vehicle.
