Abstract :
Propose a rapid sliding mode synchronization method with non-singular terminal for unmatched uncertainties of chaos systems. Through the design of switching surface of sliding mode and corresponding nonsingular terminal sliding mode control strategy, making the two chaotic systems with unmatched uncertainties can be synchronized in finite time. Simulation results show that the proposed method reduce the chattering of sliding mode control, make the synchronization time shorter and has better robustness on parameter uncertainty and uncertain external disturbances.
