| 摘 要： | 建立了4自由度1／2车辆半主动悬架模型及其状态方程。提出了一种半主动悬架阻尼模糊控制方法，它采用两个并行的模糊控制器，分别输入前、后轴3个输入量，即车身加速度、车身与车轴间的加速度差及速度差，输出前、后轴的可调阻尼控制悬架。设计了模糊控制规则，通过计算机仿真验证了这种控制算法的有效性，并证明半主动悬架与被动悬架相比能显著改善悬架综合性能。

| Abstract: | A half vehicle semi-active suspension model with 4-DOF (degree of freedom) and its state equation were built. A new method for fuzzy control on damping coefficient to semi-active suspension was proposed. The control system consists of two parallel fuzzy controllers, and three input variables (i.e., the body acceleration, the difference of acceleration between body and axle and the different of velocity between body and axle) are respectively input to the front-rear axle, the output adjustable damping of front-rear axle control suspension. We designed fuzzy control rules according to the damping control, and the efficiency of the control algorithm was validated by computer simulation that showed the general performances of the semi-active suspension were significantly improved compared with the passive suspension. |
