Aims

An increasing number of engineering applications either exploit or have to deal with nonlinear dynamical phenomena. The course presents the basic mathematical tools used in the modelling and analysis of such phenomena.

Main themes

The course is an introduction to the analysis and synthesis of nonlinear dynamical systems. The mathematical tools are illustrated on different applications, preferentially in the fields of neurodynamics, nonlinear control, and physics. Further specific illustrations are presented by the students at the end of the course.

Content and teaching methods

- Introduction to nonlinear dynamical phenomena
- Introduction to dynamical models in neuroscience
- Multiple equilibria and planar models
- Simple models of neural computation, Hopfield networks
- Gradient systems, Lyapunov functions, stability
- Feedback stabilization of equilibria
- Limit cycles
- Hopf bifuractions, asymptotic methods
- Coupled oscillators, synchronization phenomena
- Input-output tools for the analysis of nonlinear systems
- Introduction to chaos and strange attractors
