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
