Block diagram for a simulation of the analog meter modelModeling – P.L.
Kvq here is the open-loop
gain, Kvq = Kqv-1
Similar motion plan as
proposed in first lab
Saturation block models the
limited voltage range of the
AO in the myDAQ
You can construct a model in the Control &
Simulation Loop using blocks, formula nodes,
and MathScript, as shown before. But you can
also construct transfer function (TF) models.
Look under: Simulation->Continuous to find
Transfer Function. You need to define the TF as
shown on next slide.

The “CD Construct Transfer Function Model” can be
used to define models of the form we’ve constructed:
Kθ / vωn2
= 2
2
vin s + 2ζωn s + ωn
θn
Define the coefficients in
symbolic form in ascending
order on front panel
In the variables cluster, you
can assign numerical values
to each symbolic parameter
that is used in the symbolic
numerator and denominator
expressions.
