SynchroNISation and control of chaotic systems with applications

Objective



This project explores the newly-emerging fields of synchronisation and control of chaotic processes in non-linear systems.

Chaotic behaviour in electronic circuits has traditionally been considered an undesirable feature but this need not be so. Since 1990 techniques have been developed for suppressing chaos by judiciously adding appropriate external control signals. It is now possible to control systems which were hitherto considered to be operating beyond their failure boundaries. It has been known for many years that non-linear oscillators can be entrained (synchronised) to periodic forcing signals. In this decade it has emerged that non-linear systems can also synchronise, under certain conditions, when forced by non-periodic chaotic signals.

Several techniques for synchronising dynamical systems have recently been reported in the literature: threshold synchronisation of relaxation oscillations, mututal synchronisation by dissipative coupling, the Pecora-Carroll drive response method, synchronisation by error feedback and synchronisation in large ensembles of coupled active elements.

The objective of this joint research project is to exploit the analytical, numerical and experimental techniques of non-linear circuit theory and non-linear dynamics to understand the mechanisms of synchronisation in non-linear circuits and systems and to investigate applications of chaotic synchronisation and control in communications, signal processing and biomedical engineering.
