The book helps to understand the behaviour of technical and non-technical systems in
general. Emphasis is on making realistic models of physical systems, which can be applied in
animations or games. In terms of a dynamical model there is little difference between the
suspension system of a car and the motions of a flower in the wind.
It is shown that all these systems share the same basic properties, which allows the use of analogon models. A more abstract domain-independent description helps to better understand the dynamic behaviour and allows for modifications of the system in the domain that is most easily accessible.
The last chapters give an introduction to the role of feedback in dynamical systems. Examples are shown by applying these concepts to electronic simulation models with operational amplifiers. Feedback control systems are briefly introduced as a means to change the dynamical properties of a system by means of appropriate software. For more info, see the table of contents.
Extensive use is made of the modelling and simulation programme 20-sim for the simulation of
dynamical systems with iconic diagrams, bond graphs, block diagrams or equations. Exercises stimulate
exploration of the programme and experimenting with the models. The exercises are intended
to raise questions rather than being classroom problems with a straightforward solution. The
book is also a good background for 20-sim users who want to understand more of the
underlying principles of 20-sim.
