Fundamental Concepts of Lumped Parameter‐Based Multi‐Physics Modeling
Marc Budinger, Ion Hazyuk, Clément Coïc · 2019
This chapter presents the fundamental concepts of lumped parameter-based multi-physics modeling. It enables the modeling of a mechatronic type of multidomain technological systems. It reviews the modeling principles and applies to exercises that involve known effects and parameters. The modeling principles enable the review of fundamental concepts and provide an introduction to the setup and simulation of Modelica models. The chapter focuses on the network modeling level, which enables an overall representation of the system, complementary to the local view of the geometric level. Network modeling pays particular attention to the fundamental laws of physics, in contrast to the signal and functional levels, for which control signals, sensors, and physical components are represented in the same manner. Network representation is also referred to as multi-physics modeling with lumped parameters. Multi-physics modeling can generally be done in two ways: by the graphic association of two existing components or by complete or partial coding of the model.
