摘要
基于混沌同步和周期轨道理论提出一种超混沌系统自周期轨道链接式控制法。从超混沌系统状态变量的时间序列中提取周期轨道并用于对系统的实时控制 ,可使混沌系统稳定运行于某一周期轨道。将提取的周期轨道经链接组合后用于系统控制 ,可得到大量的大周期轨道。对 4阶蔡氏电路进行数字仿真实验 。
Based on the chaotic synchronization and periodic orbits theories, a new control method in which a hyperchaotic system is controlled by its own periodic orbits is proposed. Periodic orbits are extracted out from the time series of state variables of a hyperchaotic system and used to the real time control of the system. A hyperchaotic system could be made to run stably in a certain periodic orbit by this method. A large number of long periodic orbits could be obtained by applying the linking combination of the extracted periodic orbits to control the system. The simulation results for 4 order Chuas circuit are quite satisfactory.
