.Modelica.Blocks.Continuous.Derivative

Information

This blocks defines the transfer function between the input u and the output y as approximated derivative:

             k * s
     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 derivative block with parameters
b = {k,0}, a = {T, 1}.

If k=0, the block reduces to y=0.
