| 摘 要： | 选择LMS自适应滤波算法，通过调整自适应滤波器的权系数使二次性能指标达最小，根据单个样本方差的负梯度来调节权系数；得到控制输出。针对简化的车辆模型，将空钩控制、广义自适应控制与LMS自适应控制相对比。仿真计算表明，主动悬架系统LMS自适应控制策略不仅计算简单，而且理论上在主动悬架系统中的应用是切实可行的，性能明显优于其它对比控制方法。

| Abstract: | In this paper,the least means squares(LMS) adaptive algorithm is applied to active suspension system.By changing the weighting coefficients of adaptive filter,the minimum quadratic performance index is obtained.The comparative analysis on sky-hook control,generalized adaptive control and LMS adaptive control is performed for simplified two-DOF automotive suspension model.The simulation results show that LMS adaptive control is simple and feasible to apply to active suspension system with a performance apparently better than using other control algorthms. |
