By properly selecting the signal injecting position with considering the maximum gap between signals and targets, and adjusting the control time interval,we have finally obtained the efficient chaos control via numerical simulations.展开更多

We investigate the bifurcation character of the solution and calculate the Lyapunov exponents. Some deductions of this model are obtained and compared ,with experimental results. All the results show that the model is a quite reasonable one.展开更多
