| 摘 要： | 首先指出了过去在进行时延系统参数估计时所用的近似处理方法的弊端，然后就动态系统未知时延参数的估计问题提出了重构系统输入的估计方法，并以极大似然估计迭代算法为基础给出了一套估计动态系统时延参数的算法，最后，应用所提出的方法进行了仿真计算，仿真结果表明，参数估计的精度极高，这说明该方法是可靠且可行的。

| Abstract: | Firstly,this paper indicates some shortages of the old processing method for the similar problem.And then a method called system input reconstruction for estimating dynamic system's time lags and an algorithm based on maximum likelihood estimation for extracting the time lags are presented. Finally,the simulation calculations are made using above mentioned method.The simulation results show that the precision of parameter estimation is extremely high,this proves the present method is suitable. |
