Abstract :
Presents an adaptive feedback control of valve lift for an electrohydraulic actuator for camless variable valve timing engine operation. The adaptive control maintains peak value of lift in presence of variations in engine speed, hydraulic fluid temperature and manufacturing variability of valve assemblies
