英文摘要
      In this paper, the problem of finite-time synchronization of complex dynamical networks is studied by using adaptive control method. For the two cases of known and unknown coupling weights of complex dynamical networks, corresponding adaptive controllers and parameter adaptive laws are designed respectively. By using the finite-time stability theorem and the Lyapunov stability theory, the finite-time stability of error dynamic system is proved. Meanwhile, the upper bound of the settling time for synchronisation can be estimated. Finally, the numerical example is provided to illustrate the effectiveness of the proposed theoretical results.
