摘 要: | 分析了实现电磁驱动气门机构软着陆的控制困难,提出了一个开环控制策略,通过调节线圈电流来降低落座速度。进行了一系列试验来探讨电流时序及其对落座速度的影响,结果表明开环控制有一定局限性。

Initial Investigation into the Control Strategy for Electromagnetic Valve Actuation |

Abstract: | The control difficulties for valve soft landing of electromagnetic valve actuation are analyzed.An open-loop control strategy is put forward,which adjusts the coil current to reduce valve landing velocity. A series of experiments are performed to investigate the simple current sequence and its effect on valve landing velocity.The results reveal some limitations of open-loop control. |
