A New Finite-Time Observer for Nonlinear Systems: Applications to Synchronization of Lorenz-Like Systems

الملخص EN

This paper proposes a synchronization methodology of two chaotic oscillators under the framework of identical synchronization and master-slave configuration.

The proposed methodology is based on state observer design under the frame of control theory; the observer structure provides finite-time synchronization convergence by cancelling the upper bounds of the main nonlinearities of the chaotic oscillator.

The above is showed via an analysis of the dynamic of the so called synchronization error.

Numerical experiments corroborate the satisfactory results of the proposed scheme.
