| 摘 要： | 基于1 2车辆模型,在分析被动悬挂弹簧和阻尼系数对车辆舒适性影响的基础上,提出并深入研究滤波输出反馈控制策略。研究表明,在对悬挂弹簧和阻尼系数进行主动滤波的基础上,采用输出反馈控制,能大幅度衰减车辆在低于和高于车轮频率范围内的车体起伏和俯仰运动,提高车辆的乘坐舒适性。仿真结果演示了主动悬挂的性能并验证了结论。

| Abstract: | Based on half-car model and analysis of the effect on vehicle riding comfort of increasing passive spring constant and damping constant coefficients, active filtered plus output feedback control strategy is proposed and studied in detail. It is shown that heave and pitch motions of sprung mass can be mitigated by using output feedback plus active filtering of spring and damping coefficients above and below wheel frequency. Vehicle riding comfort is enhanced too. Simulation results demonstrate the performance of active suspension and verify the study results. |
