Abstract: |
In this paper, the finite-time synchronization of hyperchaotic Lorenz system is studied.Based on the Lyapunov stability theory, it is proved that finite-time synchronization for hyperchaotic Lorenz systems with certain or uncertain parameters can be achieved with some suitable controllers.Numerical simulations and circuit implementation are taken to illustrate that the theoretical analysis here is effective. |
