N2 - This paper presents detailed modeling of a novel electro-hydraulic variable valve actuator for internal combustion engines that is capable of continuously varying valve timing and dual-lift. First, nonlinear mathematical system model is developed component-by-component, considering electromagnetic, mechanical, and fluid dynamics, time delay and time-varying parameters. Second, in order to develop a control-oriented model, order of the full order nonlinear model is reduced. Calibration and validation experiments are conducted for the reduced order nonlinear model using a test bench. The key time-varying parameters are determined using the test data through the Least-Squares optimization. With the identified and calibrated model parameters, the simulation results are in good agreement with the experimental ones under different operational conditions.
