Stefan,
  There is a PID controller Type in the standard controllers library. I 
haven't tried to do so but you may be able to set the integration and 
differentiation gains to zero and simulate proportional control only. As 
another alternative, there is a proportional only controller model in 
the TESS Controls Library.
Best,
 David
