blockFirstOrder

First order transfer function block (= 1 pole)
Diagram of FirstOrder

Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).

Information

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
