Right now I am mainly concerned about linear state space. There are a few
things I think about then in come to feedback. I also need to do estimation of
constants in the model as well as check how well the dynamics fit with the
theory.
It is goint slowly forward usually an hour a few each day.
I did, even wrote a diploma thesis on that subject, but this was some 40
years ago... Since then, I rather managed people doing research on it.

Fuzzy control is not suitable for everything but it does some things
very well.
I became interested in it when I started experimenting in autopilots for
sailboats. (Power boats tend to be much easier)
There is some really horrible autopilot software out there. Its amazing

I thought the fuzzy thing where handled by adding noise with or without
filtering to model and start with the case then system is well known.

Yes a few, or actually two, both related to state feedback control and linear
state space model.
(1.)
Then using state space model and integrator I want to integrate error between
where signal is expected to be and there measurement suggest it is. As is now I
integrate error between reference

There is also a lot of developed open source Fuzzy logic libraries.
Do a search for "Fuzzy Logic Open Source".
Like everything else, some of it is good, some of it is garbage.

If you are researching loop control theory, you should also look at
Fuzzy logic controllers.
There are some simulator software out there that allow you to compare

It does seem odd.
The mail server thingy doesn't think that there have been any

something wrong with the EMC server, or is it my provider? Or are there no more
