【摘要】 半主动悬架系统自适应模糊控制器的应用是为了提高汽车悬架的阻尼效果和操控性。建立 4自由度 1 /2车辆模型 ,在此模型基础上 ,设计了模糊控制器 ,论述了半主动悬架系统的模糊控制方法 ,说明此方法对悬架质心加速度、轮胎动载荷和悬架俯仰角等性能的提高有益。对悬架在各种输入激励下的仿真效果与被动悬架作了比较 ,结果令人满意。更多还原

【Abstract】 In this article ,an adaptive fuzzy controller is designed to improve damping and ride quality of car suspension system.A half-car model with four DOF is used to simulate the system. The adaptive fuzzy logic control method of the semi-active suspension system is described,and it has improved the suspension system such as acceleration of its body,suspension deflection,tire deflection and the pitch angle. The performance of adaptive fuzzy logic controlled semi-active suspension is compared with that of passive suspension system in several simulated scenarios.更多还原
