This course focuses on modelling and simulation of the behaviour of simple multidisciplinary systems. It is an allowed prerequisite for 191211110 Modelling and simulation. It comprises 5 EC and is part of EE Module 6: Systems & Control.
The aim of this course is to learn how to model and analyse the behaviour of physical systems, in which multiple physical domains can be present. Examples are a loudspeaker or an electric motor. Bond graphs are used as a modelling language: the system behaviour is represented in terms of elementary behavioural concepts and their relations, independent of the physical domain. This port-based modelling approach is based on the use of the concept of energy as a conserved physical quantity. The interactive simulation program 20-sim is used to simulate and analyse these dynamic models. The use of numerical solution methods for simulation is discussed as well with the aim to be able to find the proper numerical method and its settings for the simulation of specific dynamic models and to judge the accuracy of the results.

Assessment
The exam will consist of two tests which will together be weighed (30% and 70%) to one grade. This combined grade needs to be 5.5 or higher to pass. If not, there is one 100% resit which needs to be scored 5.5 or higher to pass as well.
