| 摘 要： | 预测控制（包括轴距时间延迟）具有改善系统动态性能的能力，对性能指标的频率成型则可以改善乘坐舒适性。结合以上两种方法，提出了一种算法用于主动悬架控制策略的设计，并在时域和频域利用此算法对一个五自由度主动悬架车辆模型进行仿真，检验了算法的可行性和控制效果。

| Abstract: | Preview control has the potential of improving the system dynamic behavior while frequency weighting can improve ride comfort.In this paper, a control strategy based on preview control and frequency weighting is proposed.Based on simulations of a 5-DOF model of active suspensions,the feasibility and the control effects of the algorithm are examined in both time and frequency domains. |
