用VAX—11 RGL图形库输出频域响应曲线

OUTPUTING THE FREQUENCY RESPONSE CURVE WITH VAX-11 RGL GRAPHICS LIBRARY

本文介绍了计算频域响应的一个算法子程序(PMAG)和如何使用VAX-11RGL图形库输出频域响应曲线(即奈奎斯特图和伯德图)。并通过输出某二阶系统频域响应曲线的实例,具体介绍该子程序的使用方法。

In this paper, the subprogram (PMAG) for the computing frequency response and the output of the frequency response curve (i.e., Nyquist plots and Bode plots) with VAX-11 RGL (REGIS GraPhics Library) is in troduced. And the use for the subprogram is presented by outputing an example of second-grder system frequency response.
