摘要: 研究了约瑟芬电路耦合的量子细胞神经网络混沌系统的追踪控制问题,设计了一个非线性控制器,使得受控系统追踪任意给定的参考信号,并利用Lyapunov方法从理论上证明了该系统按指数速度收敛到给定的参考信号,同时实现了该系统与R?ssler混沌系统的异结构混沌同步。数值仿真进一步表明了该方法的有效性。

Abstract: Tracking control of a hyperchaotic system called the Josephson-circuits-coupled Quantum Cellular Neural Network is studied. A tracking control method is proposed for this chaotic system and it is proved by means of the Lyapunov function that this method can make the system approach any desired smooth orbit at an exponential rate. The synchronization with R?ssler’s chaotic system is also presented. Numerical simulations are given to illustrate the effectiveness of the proposed method.

Key words: quantum cellular neural network, Josephson junction, tracking control, synchronization
