摘要
采用非线性方法 ,它以不稳定、非平衡、无序、不确定和非一致为特征。阐述了混沌系统的实现 ,介绍了参数估计的混沌方法。放弃了测量大量数据的做法 ,而是比较两条运动轨道的弯曲状态来实现估计。最后给出了二阶系统和三阶系统的仿真结果。
Being contrast to existing methods for parameter estimation with linear tools that emphasize the stability, equilibrium, order, certainty and homogeneous, a nonlinear point of view is proposed with characteristics of unstability, non-equilibrium, disorder, uncertainty and inhomogeneous. The realization of chaos systems is discussed. The chaos method of parameter estimation is introduced. The simulation results for two-dimensional and three-dimensional systems are given respectively.
