Automatic optimization of high order control loops - using State observer.

I developed a simple algorithm that optimizes closed loops in time domain by
using the criteria:

Integral abs|e| dt > MIN (any other criteria could also be used)

The algorithm consists of a 3 dimensional grid for Kc, Ki and Kd that calculates all combinations of them and finds the lowest value (MIN), generally called brute force method.

Maybe someone can find a better solution and can show it.

The best I can do you can see on http://home.arcor.de/janch/janch/_control/20071103-pd5 (pid)z1z2/ Page 2 Optimal feedback control !!!
