摘要
本文利用条件数的链式性质,研究了大系统辨识中存在的数值问题,证明了关于参数辨识问题的条件数一般随着阶数增加而严格地单调增加。
In this paper,the numerical problems of identifying large scale systems are considered by use of the chain properties of the condition number. It is shown that generically the condition number associated with the parameter estimation problem strictly monotonically increases as the system order n increases.
