Hello colleges
I am doing simulation in Matlab Simulink and I cross on one problem. Before signal goes to PI controller I make a sum of measured value (which in my case is constant) and desire value (also constant). If I run simulation nothing happened. Than I put in my simulation STEP with innitial value (measeured value) and Final value(desire value). If I run simulation with this configurations PI controller is tracking my desire value from zero and not from my measured valued like I want.
What input signal can I set or any other solution would be great. Thank you very much for your response.

First of all it is not the sum of desired and measured values, it should be the difference, error = desired value - measured value. For an example check:
