单模激光Lorenz系统与3D混沌系统之间的混沌同步

研究了异结构混沌系统之间的同步控制问题.采用非线性反馈控制方法实现了3D混沌系统和单模激光Lorenz混沌系统之间的混沌同步.根据系统的稳定性理论,得到了非线性反馈控制器的结构和反馈控制增益的取值范围.仿真模拟的结果表明:目标系统和响应系统达到完全同步,两系统状态变量随时间的演化轨迹完全一致,并且误差变量经过短暂的时间序列以后始终平稳地趋于零.仿真模拟的结果证明了这种方法的有效性.

Chaos Synchronization between Single-Mode Laser Lorenz System and 3D Chaotic System

The synchronization controller was designed to synchronize chaotic systems with diverse structures.Chaos synchronization between the 3D and single-mode laser Lorenz systems was realized via nonlinear feedback control.The feedback controller was designed based on stability theory,and the area of feedback gain was taken.The artificial simulation results show that global synchronization between the 3D and single-mode laser Lorenz system is realized,and the orbit of the response system is exactly the same as that of the target system.The error signals approach zero smoothly and quickly.The artificial simulation results show that this control method is commendably effective and feasible.
