The present invention is directed to reduce the number of measuring processes of an actual apparatus. A final model for estimating the behavior of an engine 3 is generated by the following procedure. First, a simulation model in which physical properties of the engine 3 are considered is set. Next, measurement is roughly performed by an actual apparatus. Based on the difference between the simulation data and the measurement data, a correction function is Err, 130 derived. By combining the physical model and the correction function Err, 130, a final model is obtained. By using the final model, a final adaptive value is determined. |
