I limited the output to +/1 or +/- 100%. The response to the distrubances will not be any different than the response to the step changes in position set point. Why would they be different? Add your own distrubances. I show the gains, units and formulas necessary to reprodiuce my results. In any case simple PID with calculated gains easil wins! I told you it would.

Why should I bother? I proved what I wanted to. You won't meet me half way by answering any questions. As Tim says, "your receiver is broken" you don't listen or don't understand. You are on your own.
