摘要
研究了异结构混沌系统的自适应函数投影同步及未知参数的辨识问题.基于Lyapunov稳定性定理和自适应控制技术,构造了自适应控制器和系统未知参数的辨识法则,实现了异结构混沌系统的自适应函数投影同步.以著名的Lorenz系统和Lü系统为例进行了数值仿真,仿真的结果表明所构造的自适应控制器的有效性和系统未知参数辨识法则的正确性.
The problems for adaptive function projective synchronization and unknown parameters identification of differ- ent structure chaotic systems were researched in this paper. Based on Lyapunov stability theorem and adaptive control tech- nique, We constructed adaptive controller which can realize adaptive function projection synchronization between the differ- ent structure chaotic systems, and identification rules of systems~ the unknown parameters, with famous Lorenzs system and Ltisystem as numerical simulation example, the results of simulation demonstrated the effectiveness of the adaptive con- troller and the correctness of unknown parameters identification rules.
