| 摘 要： | 提出了一种基于状态观测器参数控制噪声干扰下的混沌数字通信控制方法。利用一混沌系统驱动另一混沌系统产生出理想的输出波形,将该控制方法用于混沌控制;根据噪声干扰下的系统方程构造出状态观测器,并将该状态观测器用于具有测量噪声、输入噪声干扰的混沌系统和Lorenz混沌系统的控制;改变观测器的作用范围,可以将混沌系统稳定到固有的区域内。仿真结果证实了该控制方法的有效性。

| Abstract: | The control method of state modulator is used to control chaos in the paper. The state controller is constructed on the basis of the system equation in the presence of noise interference and used to control the chaotic Lorenz system interfered by measure and input noise. As the operation range of state observation is changed, the method can stabilize the original equilibrium point or stabilize the systems to the new equilibrium point. The simulation results prove that the method is effective. |
