【摘要】 文中提出了联合线性和模糊逻辑控制的 4自由度汽车主动悬架。该主动悬架以线性控制为主 ,模糊逻辑控制为辅 ,前者以车身加速度作为控制量 ,后者以车身的垂直速度与俯仰速度的线性组合和车身位移作为模糊控制规则的输入变量。最后用Simulink进行仿真 ,并把所得结果与被动的结果进行比较 ,说明该系统对提高汽车的平顺性是非常有效的更多还原

【Abstract】 This paper presents a 4 DOF automotive active suspension with the combination of linear control(principal)and fuzzy-logic control(complementary).The vertical acceleration of the vehicle body is taken as the control variable for linear control,while the input variables for fuzzy-logic control are the displacements and the linear combinations of the vertical and pitching angular velocities of the vehicle body.The system is simulated with SIMULINK and the result is compared with that of passive suspension.It indicates that the proposed active suspension system is more effective in improving ride comfort of the vehicle.更多还原
