The Worst and Best Control System

Page 1: Definitions Page 2: Worst system if using just PID PAge 3: Best system with additional functions (State Observer)
See for details http://home.arcor.de/janch/janch/_news/20071219-stateobserver /
One can't have better results if just using a PID controller and testing under the same conditions (IAE criterion).

On page 3 the disturbances don't disturb at all. Did you forget to implement them?

So what IAE coefficients did you use? The values shown in the PDF are for ITAE and they are close but not right.
BTW, I am still waiting for the definition of best for the thread you started on 23 Nov. IAE? ITAE? SSE?
