Engine modeling based on projection method and conservation laws

To realize the concurrent development of engine hardware and control software, a rapid modeling method has been proposed based on "projection method" for mechanical portions and conservation laws for the other portions. Those methods can preserve the assembling model components of the actual engine represented by the visual image. In order to realize the rapid modeling environment, the concept of "base model" and "model library" has been also introduced. The base model defines partitioning of engine model and the interfaces among the model components. It can be used as the template for the required engine model. The model of a targeted subsystem control, an actuator control as an example, can be rapidly developed abstracting the necessary portions which are revised or simplified according to the required fidelity.
