摘　　要：研究了一类混沌系统控制器的设计问题。对该类系统利用一个非线性控制器可以使耦合系统之间的变量达到混沌同步。借助李雅普诺夫函数稳定性理论,证明了该混沌同步的稳定性定理;并通过数值仿真实现了驱动系统与响应系统的混沌同步,从而进一步证实了定理的正确性与有效性。In the paper,the design of controllers of a class of chaotic systems is presented. By means of nonlinear controller we can construct a control law to implement the synchronization between the coupled chaotic systems. The stability theory of chaotic synchronization is proved based on Lyapunov stability theory, and the simulations show that the class of chaotic system can be controlled by using the method. The result verifies its correctness and effectiveness.
