摘要
本文介绍用伪随机信号进行系统辨识的计算机辅助测试系统。通过浆纱机中一个气动系统的实例,提出并解决了辨识中的若干实际问题。借助计算机可获得该系统的脉冲响应、幅相频特性,并绘制出图形,拟合传递函数等。该软件适用于APPLEⅡ微型机,具有一定的通用性。
The system with computer aided test for system identification by pseudo-random signal is introduces in this paper.As
an example in a pneumatic system of a sizing machine several practise problems of the identification are put and settled.It is possible to
obtain the pulse response and transfer locus,to plot the graphs and to fit transfer functions with the aid of the computer.As being appli-
cable to APPLE Ⅱ this software has a certain interchangebility to other control systems.
