首先讨论了时间连续驱动混沌同步非线性观测器的线性化误差动力学方程的稳定性 ,给出了关于观测器渐近稳定性的判别准则 .随后通过理论分析和数值仿真发现 ,在时间离散驱动下 ,只要满足一定条件 ,观测器与原系统仍有可能达到同步 ,而不管在连续驱动时是否有渐近稳定的同步观测器存在 .最后推导出了时间离散驱动时混沌同步非线性观测器的渐近稳定性的判别准则 ,仿真实验结果验证了该准则的正确性 .
Firstly, the stability of the linearized error dynamics equation for time-driven chaos synchronization nonlinear observer is discussed, and the criterion for the asymptotic stability of the observer is given.And then, through theoretical analysis and numerical simulation, , As long as certain conditions are satisfied, it is still possible for the observer to synchronize with the original system, regardless of whether there is an asymptotic stable observer in the continuous drive. Finally, the chaos synchronization nonlinear observer Asymptotic stability of the criteria, the simulation results verify the correctness of the criteria.
