基于离散线性系统的稳定性理论,提出了Roessler混沌系统的一种追踪控制方案,实现了Roessler系统对任意给定参考信号的追踪,并且在理论上证明这种控制方案是按指数收敛的.数值仿真表明,该控制方案不仅可以对给定参考信号进行追踪,而且响应系统可以与驱动系统(同结构、异结构均可)同步.
This paper presents a strategy of the Roessler' s chaotic system tracking control based on the theory of stability of the linear system. This strategy can track all kinds of reference signals. It is also proved that the strategy can make the system approach to any desired smooth orbit at an exponential rate. Numerical simulations have shown the proposed strategy can not only trace the given reference signals, but also synchronize structures, including self structures and diverse ones.
