Abstract: Robust finite-time chaos synchronisation of unified chaotic systems is investigated in this paper. Based on the Lyapunov stability techniques, feedback control is presented to achieve finite time synchronisation for unified chaotic system with uncertain parameters. It should be notice that the proposed controller is robust, and the structure of the controller is realised easily. Finally, simulation results for the Lorenz, Chen chaotic systems are provided to illustrate the effectiveness of the proposed scheme.

Keywords: uncertain parameters; unified chaotic systems; finite time; chaos synchronisation; robust control; uncertainty; feedback control.
