Hi there.
In another forum I have been talking about closed loop control and found this circuit that seems to do what the group is trying to build.
That is an automatic gasious fuel air mixer with feedback.
Some differences, they don't need the push pull circuit at the end because they have servo motors
The set point needs to be done from O2 sensor ( I wonder how many newbies like me have come here asking about something like this using analog parts or an arduino ? )
A narrow band sensor would be nice a wide band may be required ( 0-1 volt narrow 0-5 volt for the more precise wide )
Where is s good place to look for something like this to adapt?
If I had to guess it was designed to use something like a dual supply OP-amp and these guys are interested in single supply.
It's been a lot of years since I played with any of this stuff.
I can look at the block diagrams and tell you what they are doing, but I can't recall much else about how to design something like this or where I would even look for help.
