Abstract:

 A discrete three-dimensional hyperchaotic system，a two-dimensional Henon map and the control of chaos and hyperchaos by means of prediction feedback have been realized in circuit. The analytic conditions that the systems are stabilized in period orbits are obtained by mathematical analysis and the experimental results are in good agreement with the results by analyzing theoretically. 

Key words: discrete system, circuit experiment, method of prediction feedback, control of chaos and hyperchaos
