摘　　要：以提高车辆减振性能为目的,提出一种基于降低悬挂系统传递至车体平均功率的功率反馈主动控制算法。以某轮式车辆四分之一车辆二自由度悬挂系统模型为研究对象,基于时域和频域相结合的方法对算法性能进行分析和评价,并分析权重系数取值对算法性能的影响。结果表明:功率反馈控制算法能够显著改善车辆的乘坐舒适性和操纵稳定性,提高车辆减振性能。In order to improve vehicle＇s shock absorbing property, a power feedback active control algorithm based on the reduction of the average power transferring from suspension systems to vehicle＇s body was put forward. The dynamic model of a quarter of the vehicle with a two-DOF suspension was chosen as a research object, and the performance of the control algorithm was analyzed and evaluated in time-domain and frequency-domain. The results show that the power feedback active control can obviously improve riding comfort, handling stability and shock absorbing property of the vehicles.
