Finite-time synchronization of complex dynamical networks with nonlinear couplings and uncertainties via adaptive fault-tolerant control

In this paper, the problems of finite-time synchronization control of complex dynamical networks with nonlinear couplings and uncertainties are considered using adaptive fault-tolerant control methods. The failure of complex network system is considered. The closed-loop system is still stable by designing adaptive fault-tolerant control strategy. For the nonlinear coupling function and unknown topology, the unilateral Lipschitz condition and adaptive gain estimation are used. Finally, the feasibility of fault-tolerant control strategy is verified by numerical simulation.
