[avr-chat] Autotuning a PID controller

[Royce Pereira]

Hi all,
Sometime back I had asked the lists' help in PID theory. I am grateful for all 
the replies- I was able to design a couple of PID temperature controllers.

In those designs I have to enter KP, KI, & KD manually, by a trial & error 
method.

Is it possible for the controller to find out these values automatically say 
based on rate of rise of temperature etc..?

I'd appreciate some help in developing an algorithm for the same.

Thanks & regards,

--Royce.
