摘　　要：建立了车辆整车7自由度模型的主动悬架控制的系统状态方程模型,设计了两种模糊控制策略,方法一针对整车模型,采用一种控制方法,方法二针对整车模型的运动方式,设计不同的模糊控制器,垂直振动模糊控制器,俯仰振动模糊控制器,侧倾振动模糊控制器和逻辑控制器,仿真结果表明,所设计的模糊控制器对提高车辆的舒适性与操纵稳定性有较好的效果.This paper established an active suspension system for seven degrees of freedom model of a whole body. Two kinds of fuzzy control policy were designed. According to the whole vehicle system, one control policy was described in method one. And the vertical motion fuzzy logic controller, the pitch motion fuzzy logic control- ler, the roll motion fuzzy logic controller and the logic controller were established in method two. The simulation results indicate that the ride comfort and the control stability are ameliorated by the proposed controller.
