【摘要】 在1/4车辆悬架数学模型的基础上,分别采用T S和Mamdani模糊控制策略,建立模糊模型的半主动悬架控制系统,分析和比较了两种控制系统的性能,设计了基于CIP 51为核心的单片机控制器,并进行了半主动台架试验.计算和试验结果表明,模糊控制器均能有效地控制半主动悬架系统,提高车辆的乘坐舒适性,改善车辆的性能.与普通Mamdani模糊控制相比,T S模糊控制器具有设计简单,运算速度快,便于实时控制的优点,验证了T S模糊控制方法的有效性和优越性.更多还原

【Abstract】 Based on the mathematic model of a quarter of vehicle suspension, the fuzzy control model of semi-active suspension was established by using T-S and Mamdani fuzzy control strategies. The perfor-(mances) of two control systems were analyzed and compared. The controller with CIP-51 as its core was designed. Based on these, experiments were carried on. The simulation and experiment results show that the two fuzzy controllers can control the semi-active suspension effectivedly, improve vehicle’s perfor-(mance and increase ) the riding comfort of vehicle. Compared to Mamdani fuzzy controller, T-S controller can be designed easily, controlled quickly and run rapidly.更多还原
