摘要
文章采用工程易于实现的模糊控制方法,设计了磁流变半主动悬架模糊控制器;进行了车身垂直加速度、车速采集和减振器驱动等硬件系统的电路设计;软件设计中移植了嵌入式操作系统μC/OS-Ⅱ,采用多任务程序的设计方法;利用自主开发的磁流变减振器以及控制器,对国产昌河CH711A轿车进行改装并进行实车道路对比试验;实验表明,设计的磁流变半主动悬架控制器可以有效地降低车身垂直加速度,改善整车行驶平顺性。
In this paper,the fuzzy control,which is easily implemented in the practice,is used to design the fuzzy controller of the semi-active suspension（SAS） based on magneto-rheological（MR） damper.The hardware circuit is designed in view of processing vertical acceleration,vehicle speed signal,MR damper drive,etc.,and the software design is mainly based on the μC/OS-II-imbedded real-time operating system and multitask program design method.The modification and road test for the home-made vehicle CH711A are made based on the self-developed MR damper and its controller.The experiment results show that the proposed controller of SAS based on MR damper can decrease vertical acceleration of vehicle and improve ride comfort effectively.
