Abstract
To achieve the low carbon society, the evolution of internal combustion engine efficiency and the addition of electric devices have been required. As a result, control systems have become more complex, which in turn, demands improvement of development efficiency. In this study, the new plant model and new virtual environment are established for the purpose of improving the efficiency of the control system development. Furthermore, by using the new modeling method, the improvement of development efficiency of the plant model and virtual environment is made possible.
