- the model C ′ is used for calculation.
- one parameter may be calculated with the model C ′, and the other parameter may be calculated with the small model A.
- the calculation capability of the control device can be more effectively utilized by calculating with the large-scale model C ′ with priority given to parameters that require higher accuracy.
