Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This blocks defines the transfer function between the input u and the output y as first order system:
k
y = ------------ * u
T * s + 1
If you would like to be able to change easily between different
transfer functions (FirstOrder, SecondOrder, ... ) by changing
parameters, use the general block TransferFunction instead
and model a first order SISO system with parameters
b = {k}, a = {T, 1}.
Example:
parameter: k = 0.3, T = 0.4
results in:
0.3
y = ----------- * u
0.4 s + 1.0
