Symmetries and semi-invariants in the analysis ofnonlinear systems

This book details the analysis of continuous- and discrete-time dynamical systems described by differential and difference equations respectively. Differential geometry provides the tools for this, such as first-integrals or orbital symmetries, together with normal forms of vector fields and of maps. A crucialpoint of the analysis is linearization by state immersion. The theory is developed for general nonlinear systems and specialized for the class of Hamiltonian systems. By using the strong geometric structure of Hamiltonian systems, the results proposed are stated in a different, less complex and more easily comprehensible manner. They are applied to physically motivated systems, to demonstrate how much insight into known properties is gained using these techniques. Various control systems applications of the techniques are characterized including: computation of the flow of nonlinear systems; computation of semi-invariants; computation of Lyapunov functions for stability analysis and observer design. Most results are derived for continuous- and discrete-time systems showingreaders how to recognises when their own techniques are valid in both cases. Rigorous mathematical treatment in a simple style allows in-depth understanding to be easily acquired. Self-contained presentation requires only the most basic of mathematical knowledge of real analysis, linear algebra and systems theory. INDICE: Part I: Theory. - Introduction.
