摘要
针对电动机械式自动变速器换挡时间较长的特点,对电动AMT选换挡电机进行分析和建模;基于动态滑模理论,提出了一种换挡电机动态滑模控制方法,并将它应用于电动AMT汽车选换挡执行机构的位置跟踪控制。仿真与试验结果都表明,与常规的PID控制器和滑模控制器相比,动态滑模控制器响应速度快、鲁棒性好、跟踪精度高,能有效地改善AMT的换挡品质。
Modeling and analyses were carried out on a electric AMT,in order to assuage the long gear selection and shifting time problem of AMT.Based on the theory of sliding mode control,gear selection and shifting dynamic sliding model control was initiated,which was applied in the position track of gear selection and shifting mechanism.Both of the simulation and experimental results reveal that compared to the general PID controller and sliding model controller,dynamic sliding model controller has faster response,better robust,higher track accuracy,which improves the shifting quality of electrical AMT.
