## Über dieses Buch

Chaos occurs widely in both natural and man-made systems. Recently, examples of the potential usefulness of chaotic behavior have caused growing interest among engineers and applied scientists. In this book the new mathematical ideas in nonlinear dynamics are described in such a way that engineers can apply them to real physical systems.
From a review of the first edition by Prof. El Naschie, University of Cambridge: "Small is beautiful and not only that, it is comprehensive as well. These are the spontaneous thoughts which came to my mind after browsing in this latest book by Prof. Thomas Kapitaniak, probably one of the most outstanding scientists working on engineering applications of Nonlinear Dynamics and Chaos today. A more careful reading reinforced this first impression....The presentation is lucid and user friendly with theory, examples, and exercises."

### 1. Response of a Nonlinear System

Abstract
This chapter briefly describes why nonlinear phenomena are important to engineers. We show that during investigations of nonlinear systems one can observe phenomena which are not familiar from the linear theory.

### 2. Continuous Dynamical Systems

Abstract
In this chapter we describe in a simple way mathematical tools which are necessary in the analysis of dynamical systems. The fundamental notion of an attractor is introduced. We start from the fixed points, limit cycles and finally describe the properties of strange chaotic attractors. To complete this description we introduce Poincaré maps and Lyapunov exponents. Poincaré maps are tools which allow the system dimension to be reduced, an idea known to engineers from the stroboscopic lamp. Lyapunov exponents measure the divergence of trajectories starting from nearby initial conditions. These exponents are important since, in most engineering systems, initial conditions cannot be set or measured accurately. Additionally, we show that the analysis of the classical power spectrum can be also useful in analysing chaotic systems.

### 3. Discrete Dynamical Systems

Abstract
A discrete dynamical system is a system which is discrete in time so we observe its dynamics not continuously but at given moments of time as in the case of the Poincaré map introduced in the previous chapter. The dynamics of discrete dynamical systems is usually simple enough to be explained in detail. We use these systems to describe the main phenomena of nonlinear dynamics.

### 4. Fractals

Abstract
Fractals, objects with noninteger dimension, may at first sight seem to be unlikely candidates for any practical applications. In this chapter we introduce basic examples and properties of fractal sets starting with a classical example of the Cantor set and introduce different definitions of its dimension. Later we discuss the application of the fractal concept to dynamics and show that it is very useful in the description of strange chaotic attractors.

### 5. Routes to Chaos

Abstract
In the previous chapters we have introduced the methods for describing chaotic behaviour. Here we will observe how the behaviour of our systems changes during the transition from periodic to chaotic states. The mechanism of the transition to chaos is of fundamental importance for understanding the phenomenon of chaotic behaviour. There are three main routes to chaos which can be observed in nonlinear oscillators.
Tomasz Kapitaniak

### 6. Applications

Abstract
Chaotic behaviour occurs in a great number of practical engineering and natural systems. In this chapter we briefly present several examples of chaotic behaviour in mechanical engineering, chemical reactions, electronic circuits, civil engineering problems and fluid dynamics. These examples show the variety of possible applications of chaotic and fractal dynamics in different branches of engineering. They can be considered as starting points for readers’ own research in a chosen branch.
Tomasz Kapitaniak

### 7. Controlling Chaos

Abstract
As was shown in previous chapter chaos occurs widely in engineering and natural systems; historically it has usually been regarded as a nuisance and designed out if possible. It has been noted only as irregular or unpredictable behaviour, and often attributed to random external influences. More recently there have been examples of the potential usefulness of chaotic behaviour. It is to the potential usefulness of chaotic behaviour that we turn our attention in this chapter.
