摘　　要：本文采用自适应模糊方法设计车辆悬架半主动控制器。以模糊控制原理为基础 ,融合自适应方法 ,将模糊系统辨识和模糊控制结合起来 ,在模糊控制器内采用“软反馈” ,并对自适应模糊的控制规则进行修正。该法简化了运算 ,提高了半主动悬架控制的实时性 ,使系统的控制性能不断改善 ,达到最佳的控制效果 ,较好地解决了乘坐舒适性与驾驶安全性间的设计矛盾。Adaptive fuzzy control scheme was adopted in designing the semi-active suspension system of an automobile based on the fuzzy control principle and the adaptive scheme. Fuzzy system identification is connected with fuzzy control, adopting “soft feedback” in the fuzzy controller. Changes in the adaptive fuzzy control rule make it simpler and improve the semi-active suspension control's real-time performance. All these measures improved the system performance and bring to optimum results, achieving better solutions in the settlement of contradiction between the riding comfort and steering safety.
