Hey, I have been reading a fair few of the posts regarding PID control of the Silvia and I had a thought/question. Since the temperature/thermostat closed loop system is highly non-linear, the application of PID control is not necessarily the most ideal. I know from control systems engineering (which is what I do at uni) that PID controllers can only get so close in terms of heat recovery, tracking etc. A classic example is its use for furnaces back in the day with heat treating. Nowadays they have all shifting to fuzzy logic control which offers a very humanlike approach to control the temperature, almost the same way us humans adjust the shower taps to get the right temperature. The results are faster heat times and tighter control. Perhaps these would have little if any benefits over PID which is already well established and working for people quite well already, but since people are willing to try anything in the search for espresso nirvana, perhaps this is another avenue people could try.
As for my contribution, I am definitely interested in discussing with people ways this could be implemented, contribute my know how and try fabricating and testing such a thermostat system. I have developed working fuzzy systems at various levels already.
Sounds interesting I thought
