摘要: Abstract Variable valve opening and closing allows improvements of internal combustion engines requires precise control the camless valvetrain actuator. In this paper position tracking in electromechanical valvetrains (EMCV) is considered. One main problems EMCV actuator noise wear associated with high contact velocities during valve. The velocity can be reduced, thus, wear, by designing a controller that consists linear feedback an iterative learning (ILC). With ILC methodology every cycle feedforward signal updated based on error between actual desired position. reviewed simulation results are presented.
