Modern internal combustion engines currently use a multitude of electromechanical elements generically called actuators. Thus, within the highlevel “engine” system, each actuator can be considered an element. At a further increase in detail,aforementioned high-level components can be regarded as lower level systems themselves commonly known as subsystems, with their corresponding components. Due to this aspect, the study and design of actuators is suited to a model-based systems approach where mechatronic elements need to be modeled hierarchically. The current paper proposes a method for obtaining such a model for an Air Control Valve, using the bond graph theory. Its target outcome is a numerically computable response (position) to an applied input (voltage) while keeping internal (design) parameters explicit. The model is intended for design space exploration and virtual system integration. The resulting dimensionally homogeneous model is given as a state-space representation along its graphical form as a block diagram in addition to the augmented bond graph.
