Parameter Used By Description
T 2 — Second time constant Transfer function with two
real poles
Can take any value between
0 and T, the time span of
measured or simulated data.In the plot, drag the
magenta x left (towards
zero) or right (towards T) to
adjust T 2.Tω — Time constant
associated with the natural
frequency ωn, where Tω =
1/ωn
Transfer function with
underdamped pair (complex
conjugate pair) of polesCan take any value between
0 and T, the time span of
measured or simulated data.In the plot, drag one of the
orange response envelope
curves left (towards zero) or
right (towards T) to adjust
Tω.ζ — Damping coefficient Transfer function with
underdamped pair (complex
conjugate pair) of poles
Can take any value between
0 and 1.In the plot, drag one of the
orange response envelope
curves left (towards zero) or
right (towards T) to adjust ζ.τ — Transport delay Any transfer function Can take any value between
0 and T, the time span of
measured or simulated data.
In the plot, drag the orange
vertical bar left (towards
zero) or right (towards T) to
adjust τ.Choosing Identified Plant Structure
