Generate white noise in Modelica (SystemModeler)

I am trying to add measurement noise to a simulation. This is possible to do in for example Simulink but seems to be more difficult in Modelica and SystemModeler.

Any ideas on how to do this?

Solution

  • An alternative is to use Modelica.Blocks.Noise to avoid writing external code yourself (added in Modelica Standard Library 3.2.2 released April 3, 2016; i.e. it would not have helped when the original question was asked).

    One benefit of Modelica.Blocks.Noise is that the tricky questions with sampling, multiple seeds, etc are solved.
