| 摘 要： | 我们用BASIC语言设计了根据频响数据辨识传递函数模型（以下简称模型）的应用程序。在计算机上对八个模型的频响数据进行了辨识,结果较吻合。 一、原理和误差判定准则 1.原理 应用最小二乘原理,使试验结果C（jω1）和辨识结果Ga（jω1）的误差平方和为最小。

| Abstract: | The algorithm and the computer program TFIP used to identify the transfer function models from experimental freguency response data are presented. It is also considered how the selection of the model orders, the selections of the equationerror and real error tolerance, and the modes for updating weight coefficientsaffect the convergent speed and identification results. The new term rejectioncriterion and the method for updating weight coefficients by variable mode are proposed, the former can simplify the program, and the latter may greatly accelerate the convergence of the weight coefficients. |
