Abstract :
A control-oriented linear model was constructed for an electromagnetic camless valvetrain (EMCV) based on a gray-box approach that combines mathematical modeling and system identification. An inner-loop feedback stabilizing controller and a cycle-to-cycle repetitive learning feedforward controller were designed for the EMCV to meet the quiet-seating requirement. The performance of this control system is demonstrated by experimental results
