On Abstraction and Interpretability: A Behavioural Perspective

The process of abstracting physical systems to obtain models and interpret these for the desired purpose is considered from a perspective originating from the behavioural framework. It is pointed out that for the purpose of modelling regenerative processes or passive controllers, the behavioural framework and bond graphs are well suited. To both techniques, a brief introduction is presented, focussing on the key concepts and applying illustrative examples and a simulation.
