Abstract: In this paper, the problem of control and synchronization for hyper-chaos
system including negative capacitor. The linear-couple-controlling algorithm could
be designed using couple-controlling theory. The given algorithm owned the proerpty
of making the hyper-chaos system stabilizing in the lower field, and the problem
of synchronization for the coupled-controlling hyper-chaos system could be
transformed to the one whether the stability error of the system is changing to zero
as the time is flying combing linearization with stability theory. At the same time,
the simulation on the presented algorithm could be carried out, and the results
illustrated that the algorithm is valid.
Key Words: coupled-control, hyper-chaos, synchronization
