摘要
设计了一种统一形式的非线性状态反馈控制器,实现了一类五阶超混沌电路系统的状态变量与任意给定参考信号的追踪广义投影同步.通过取不同的比例因子和加速因子,可以快速获得与超混沌系统和多个不同维混沌系统之间的异结构广义投影同步、周期信号的广义投影同步,以及将五阶超混沌系统快速控制到周期态和期望的平衡点.数值仿真进一步表明了该方法的有效性.
A nonlinear controller is proposed to acquire generalised projective synchronization and arbitrary trajectories of full states of a fifth-order hyperchaotic circuit system. By adjusting the scaling factor and the accelerated factor, generalized projective synchronization between the fifth-order hyperchaotic circuit system and the hyperchaotic systems, chaotic systems and periodic signal can be rapidly realised, and the fifth-order circuit＇ s hyperchaotic circuit system can also be driven to arbitrary periodic orbits or fixed point rapidly. Simulation results are presented to demonstrate the effectiveness of the proposed method.
