摘要: This paper proposes a control strategy involving energy compensation for the soft-landing of an electromagnetic valve actuator in internal combustion engines. axisymmetric and cylindrical features hybrid magnetomotive force with permanent magnet electromagnet, secondary air gap to prevent irreversibly demagnetizing. It is straightforward theory which positive negative work armature stroke equalized, enabling zero landing velocity be achieved. The resultant function velocity, depends on release current that releases from one seating position, attracts opposite position. magnitude duty cycle currents are investigated via observation displacement velocity. experimental results show can greatly reduced by adjusting current, actuating power after applied.
