摘　　要：对R ssler混沌系统进行控制 ,使之追踪任意参考信号 ,讨论了该控制系统的自同步以及与Lorenz混沌系统的异结构混沌同步问题 ,并利用Lyapunov方法证明了该控制系统指数收敛到参考信号 .A novel tracking control method is proposed for the Rssler's chaotic system. It is proved by means of Lyapunov function that this method can make the Rssler's system approach to any desired smooth orbit at an exponent rate. Both the self synchronization and the synchronization with Lorenz's chaotic system are discussed as well. In the end, computer simulations are given to illustrate the effectiveness of the proposed method.
