Bond graph modeling for the simulation of an electromechanical chain

Abstract

In complex multi-physic systems such as electromechanical chains, it is necessary to establish clear and simple simulation models. This need is linked to the increase of hardware in the loop (HIL) development processes. Indeed, this way of design complex systems allows to reduce development costs. However, HIL development efficiency is linked to the accuracy of models. Consequently, complex systems must be modeled using a comprehensive approach such as bond graphs leading to equations easily implementable on simulators. This paper proposes a model of a whole electromechanical chain including some nonlinearities of parameters leading to an accurate representation of real systems.
