【摘要】 根据汽车二自由度主动悬架模型,结合振动控制的理论和技术,着重研究了被广泛应用的模糊控制、最优控制和模糊PID控制,并利用M atlab进行仿真,与被动悬架进行了比较。对车身加速度、悬架动挠度和轮胎动荷载3个性能指标进行了评价,不仅讨论了上述3种控制方法用于主动控制的优点,还指出了这些控制策略存在的不足。更多还原

【Abstract】 This paper established a two-degree-of-freedom model for automobiles′ active suspensions,with emphasis laid on the widely applied fuzzy logic control,optimal control and fuzzy PID control and in combination with vibration control theory and technique.The active suspensions are compared with the traditional passive suspensions.At the same time,both the advantages of the above three control methods and their disadvantages for active control are discussed.更多还原
