摘要
对于载噪时线性多变量系统的结构测辨,迄今还未出现很有效的解决方法,现有的方法都须人为地选择一个检验量ε,ε的取值往往要凭人们的经验。本文提出了一种新的具有递推性的结构测辨方法,该方法使用系统正常运行的数据,在载噪且噪声统计特性未知及数据较少时,可以准确地确定系统的结构不变量,同时得到系统参数的最小二乘估计值。数值实例中的仿真计算表明该方法是可靠的。
The structure identification of linear multivariable systems is a complicated
problem specially in the stochastic case。So far,no very efficient method has been
proposed.In this paper,a new recursive method is proposed for the solution
of the same problem。For this method,the residual from a least square fitting
is tested in order to determine the structure invariants exactly。The result of the
simulation example shows that this method is reliable。
