From Design to Modelling

The second question was on the necessity of the model itself. Generally, model-based control opposes to dynamics-based control. This idea was questioned because of the following reasons. 

The third question was on the productiveness of the modelling. There exist numerous numbers of models for many kinds of material. Under this circumstance, the model was proposed because we believed that general description was necessary. 

We think that the importance of model for design should be emphasized, compared to the importance of model for control. The ideal design process is a conversion process starting from function to mechanism and structure. Starting 

Material, field, and local interaction between them could be respectively described. This is because we take the strategy to develop material and field respectively. 

Relationship between the design variables and control variables could be clear. This is because the role of design and control variables is comparable. Design variables are pre-defined while control variables are changeable after the total system setup. Designers can select which is preferable.
