Modelling and simulation of the behaviour of simple multidisciplinary systems. This course is a prerequisite for 191211110 Modelling and simulation. It consists of 5 EC of taking part in the lectures and tests of the Engineering System Dynamics part of the EE module 6.|
Knowledge: the student will
Competencies: at the end of the course the student will be able to
- obtain basic knowledge in the field of dynamic behaviour of physical systems, in such a way that the obtained models are competent for the given problem context.
- obtain knowledge in the field of dynamic behaviour of physical systems, in such a way that new problems in this field can be solved either by extending the offered structures, methods and techniques, or by referring to the corresponding literature.
- be able to see relations and similarities between subjects from physics, mathematics and engineering by making use of the offered structure (that is based on these relations). As a result, being able to apply methods and techniques from a specific physical domain in other physical domains, where these methods may be uncommon.
- obtain knowledge about numerical solutions techniques for simulation.
Attitude: at the end of the course the student should be
- model and analyse the dynamic behaviour of physical systems in which more than one physical domain may play a role.
- perform model transformations using the offered systematic methods, i.e. from a domain-specific, ideal physical model, via a bond graph to differential equations, block diagram or signal flow graph.
- perform these transformations also in reverse order, while interpreting the omitted or generated information.
- create analyse and simulate models in 20-sim and to adapt them on the basis of the results. Using these results for analysis and verification of the models.
- distill model properties that are relevant for correct numerical simulation from the model, to use this information to choose a suitable numerical method; to judge the numerical accuracy of the simulation results. Being able to adapt the model on the basis of simulation properties.
- able and inclined to use the offered relations and similarities between various physical domains for a better recognition and description of dynamic phenomena in all sorts of physical systems. In other words: they are able to use the insight in analogies and apply what has been learned about one domain in another domain.
- inclined to judge the correctness of simulation results
- qualitatively and,
- up to the order of magnitude, also quantitatively
- from asymptotic and limiting results.
The aim of this course is to learn how to model and analyse the behaviour of physical systems, in which several physical domains can be present like a loudspeaker, an electrically driven fluid pump, an automotive transmission and 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 dynamical 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.|
The exam will consist of two tests which will together be weighed 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. Irrespective, the number of EC’s is 5.
