摘要
研究了基于状态观测器的一类混沌系统的投影同步问题.基于状态观测器方法和极点配置技术,设计出一种投影同步方案,使得一类混沌系统达到了投影同步.与以往的投影同步方法相比,该方法简便,易于实现,达到投影同步的时间短,并且在同步控制过程中可任意调整缩放比例因子.最后,用L系统进行了数值仿真,仿真结果进一步证明了该方法的有效性.
This paper addresses the problem of projective synchronization based observer of a class of chaotic systems. Based on techniques from the state observer design and the pole placement technique, we present a systematic design procedure to synchronize a class of chaotic systms by a scaling factor （projective synchronization）. Compared with the existing methods, this method is rather simple and convenient to realize. The rate of achieving projective synchronization is very fast. Furthermore, the scaling factor can be adjusted arbitrarily in due course of control without degrading the controllability. Finally, feasibility of the technique is illustrated for the Lü chaotic system. Numerical simulations show the effectiveness of the proposed method.
