发动机电磁气门驱动开环控制系统设计与试验

Desig n and Tests of the Open Loop Control System of Engine Electromag netic Valve Drive System

对电磁气门驱动的控制系统有3方面要求:使励磁线圈中电流快速变化、实现气门软着陆和减少能耗。从电磁气门驱动工作原理出发,针对对控制系统的要求,为用于探索性试验研究的电磁气门驱动装置研制了开环控制系统,并通过电磁气门开环系统的驱动试验检验了该控制系统的可行性。

Three requirements for the control system of the electromagnetic valve drive system are as follow:to make electric current change rapidly;to realize valve soft landing;to reduce energy consumption.Based on operation principle of the drive system of electromagnetic valves,aimed at the above requirements for the control system,the open loop control system is developed for the electromagnetic valve drive system that is to be used in trial tests.By tests,the loop control system is proved to be feasible.
