摘要
基于无源性的方法研究了两个相同的非线性系统的同步问题,证明当两个待同步的混沌系统都是半无源系统时,使用输出反馈控制律可实现这两个系统的自适应同步,文中给出了系统输出同步反馈控制律存在的充分条件,设计了同步增益的自适应调节算法,并以Lorenz系统为例,验证了该反馈控制律和自适应算法的有效性并给出了仿真结果。
The synchronization method of two same nonlinear systems is discussed based on the passive theory. It is proved that two chaotic systems can be synchronized with output feedback control law if they are all semi-passive systems. The sufficient condition of the existence of output feedback control law as well as the adaptive adjusting algorithm of synchronization are given.Taking Lorenz system as an example, the feedback control law and adaptive algorithm are validated in the simulation.
