| 摘 要： | 针对一种新的三维连续自治混沌系统的异结构同步控制进行了研究．基于Lyapunov稳定性理论，设计出一种确保系统渐近同步的非线性控制器；并且在此基础上采用参数自适应控制策略对系统中不确定的参数进行估计．从理论上证明了在系统参数未知或结构不确定时，能够实现新混沌系统和Lorenz混沌系统之间性能良好的异结构混沌同步控制，同时识别出未知参数．数值模拟结果进一步验证了所提方案的有效性．

| Abstract: | The chaotic synchronization control with diverse structures and uncertain parameters is studied based on a new continuous autonomic chaotic system. A nonlinear controller is presented based on Lyapunov stability theory, which insures the stability of chaotic synchronization. According to the strategy of adaptive control for parameters, the uncertain parameters of systems are estimated. The good chaos synchronization between the new chaotic system and the Lorenz chaotic system has been proved theoretically when the parameters are fully unknown. The unknown parameters are identified. Numerical simulations show the effectiveness of the proposed method. |
