自动测试中的系统辨识机

A system identifier in automatic testing

介绍了一种通用的动态系统辨识机，用以适应自动测试领域中的广泛需要。系统采用ARMAX模型，参数估计以最小二乘法为基础，提供了多种克服有色噪声影响的改进算法，同时利用F检验和AIC方法为判据，实现了模型阶次的辨识。系统在Windows 98下实现，作为面向自动测试的软件工具的重要组成部分，显然是十分有用的。

This paper shows a system identifier with the general purpose to meet the needs of the automatic testing．The system uses ARMAX as system model． The parameter estimation is based on the LS algorithm and the system supplies a various new methods to overcome the influences by the non－white noises．The order of system also could be identified with critireas on F－Testing and AIC method．The system is implemented under the Windows98．It is very useful as an important component of software tool for automatic testing．
