Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This example shows the response of a PT2 defined by its transfer function

            1
H(jw)=-------------------
      1 + 2 d jw + (jw)^2

Frequency performs a logarithmic ramp from 0.01 to 100 s^-1.

Plot the magnitude locus (in dB) dB versus lg_w and the phase locus versus lg_w.

Parameters (5)

d

Value: 1 / sqrt(2)

Type: Real

Description: Damping coefficient
