摘要: 以一维耦合映象格子为对象,研究了相位共轭波时空混沌系统特性.基于Lyapunov稳定性定理,通过选取耦合参数,实现了CO2激光器对相位共轭波时空混沌系统的控制,以及驱动多个相位共轭波时空系统达到并行同步.数值模拟结果显示,耦合参数对相位共轭波时空混沌系统的控制和同步速度有影响,即耦合参数越大同步时间越短.Abstract: Taking an one-dimensional coupled map lattice as an object,the characteristics of phase-conjugate wave spatiotemporal chaos system are investigated.Based on the Lyapunov stable theorem,the control of phase-conjugate wave spatiotemporal chaos system is achieved,and the multiple phase-conjugate wave spatiotemporal chaos system is driven into the parallel synchronization by the CO2 laser through choosing the coupling parameter.Numerical simulation results show that the coupling parameter has influence on the control and the synchronization speed of the phase-conjugation wave spatiotemporal chaos system.The greater the coupling parameter,the shorter the synchronization timeis.
