for my simulink model i need a variable time delay, therefore i tested it by generated a s function out of it because i need the whole model as a s function. by comparing the two results i got something very strange: the generated s function provides me an amplified and phase delayed signal. does someone know the reason why this is happening? how can this problem be solved?
Andreas: Since you seem to have narrowed down the issue to a very simple model, I would highly recommend that you report this to MathWorks Tech Support with the model so that they can determine whether this is a bug. It's hard for me to judge anything without looking at the model, so I think it might be best if Tech Support investigates this further.
