Based on fractional calculus predictor-corrector algorithm
the fractional-order hyperchaotic Chen system is investigated numerically
and the simulation results show that the lowest orders for hyperchaos in hyperchaotic Chen system gets 3.8. According to the stability theory of fractional-order system
an improved state-observer is designed
and the response system of generalized synchronization is obtained analytically
whose feasibility is proved theoretically. The synchronization method is adopted to realize the generalized synchronization of 3.8-order hyperchaotic Chen system
and the numerical simulation results verify the effectiveness.
