Abstract: One the most important properties of the dynamical system is the complete synchronisation phenomenon. In this document, we are working on creating a non-linear controller for the success of the synchronisation process between two identical systems, each of them seven-dimensional. The linearisation and Lyapunov methods have been used as analytical methods to demonstrate the phenomenon. The results showed that the linearisation method does not need to update the function as in the Lyapunov method, and therefore it is effective to achieve synchronisation phenomenon with better results than the Lyapunov method. Digital emulation was applied to the mathematical system with control system and the error dynamical system, the results are excellent. We've studied complete synchronisation phenomenon according to Lyapunov and linearisation, and compared their results. Finally, we applied the current system and presenting it in a new attractor and compare these results with other similar ones.

Keywords: chaos; Lyapunov; linearisation; complete synchronisation; non-linear dynamical system.
