| 摘 要： | 由于难以采用传统的闭环控制方法控制发动机电磁气门驱动（EVA），在大量开环试验的基础上提出一个EVA过渡过程闭环控制的新方案，该方案由两个部分组成：运动过程控制和落座控制。运动过程控制能实现较小的落座速度，落座控制能保证落座的成功。在研制的EVA上进行的试验表明，采用这种控制方法能够得到小于0．2m／s的落座速度，但EVA连续动作时平均落座速度大于单次动作的落座速度。

| Abstract: | As the conventional closed-loop control method was unfeasible for electromagnetic valve actuation(EVA) control,a new closed-loop control method for EVA transition was proposed based on a lot of experiments.The control consisted of two portions.The first portion was armature motion control,which was aiming to a low seating velocity.The second portion was seating control,which was to ensure the landing of the armature(valve).Experiment on this EVA shows that seating velocity of less than 0.2 m/s could be reached by this control method.However,there was a higher seating velocity for EVA continuously working than that for EVA transition in single-acting. |
