Abstract:

A scheme for controlling hyperchaos in the RCLSJJ array is presented by applying periodic perturbations to the external bias current. Numerical investigations show that this scheme can be effectively used to control hyperchaos states in this array and to make them enter into stable periodic states. And the different stable period states with different period numbers can be obtained by appropriately adjusting the amplitude and frequency of the
 perturbation signal. Moreover, the inphase states were discussed in the controlled array system.
