| 摘 要： | 为解决电控机械式自动变速器（AMT）动力中断时间过长的问题，研制了一种基于电磁直线执行器的时序重叠换挡系统。介绍了关键部件电磁直线执行器的结构和工作原理，建立了机、电、磁耦合的系统模型，并通过实验进行了性能分析。提出了时序重叠换挡的控制策略，基于二自由度控制原理设计了位置复合控制器。仿真和实验结果表明，提出的位置复合控制器具有较好的系统响应和扰动抑制特性；在转速差为500 r/min、被同步惯量为0.01 kg·m2条件下，采用时序重叠换挡方式由2挡换至3挡的换挡时间约为130 ms，时序重叠控制减少时间约20 ms，换挡时间缩短15%以上。

| Abstract: | In order to shorten the power interruption duration of AMT， a time-overlapping gearshift system was developed based on the electromagnetic linear actuators.The structures and working principles of the electromagnetic linear actuators were presented.A coupling system model including mechanical， electric circuit and magnetic circuit subsystems was built.The characteristics of the actuator were analyzed by experiments.The time-overlapping control strategy was presented， and the position compound controller was designed based on the two-degree-of-freedom control principle.The simulation and experimental results show that the proposed position cascade controller achieves good response and disturbance rejection performance.When the speed difference is as 500 r/min and the synchronized equivalent inertia is as 0.01 kg·m2， gear-change from 2nd to 3rd， the time is about 130 ms， the time-overlapping control method has about 20ms time-saving， and the total time is reduced by more than 15%. |
