摘要
利用n阶驱动系统的标量输出信号及其连续的n-1阶导数作为状态变量,得到一个具有Brunowsky规范形式的n阶重构系统.对该重构系统设计状态观测器,并将其作为响应系统.此时只需传输由输出信号与其连续的n阶导数的线性组合构成的标量信号,便可实现混沌系统的同步.当传输信号仅为标量输出信号时,还可通过对重构系统设计扩张状态观测器,挖掘可测同步误差中所隐含的信息来实现混沌系统的同步.对Rossler系统的仿真证明了该方法的有效性.
An n-order reconstructed system is designed in Brunowsky canonical form by using a scalar output signal of n-order driving system and its successively n-1 order derivatives to reconstruct state variables. A state observer is designed for the reconstructed system and regarded as the response system. Synchronizing chaos is realized via only transmitting scalar signal consisting of output signal and its successively n order derivatives. When the transmitted signal is only scalar output signal, synchronizing chaos is realized via designing the extended state observer for reconstructed system and collecting the information wrapped in observable synchronizing error. The simulation result of R ossler system manifests the effectiveness of this method.
