Analog PID controller designed from scratch in a very long journey of trying, failing and learning. It seems, anyway, that I managed to get some reasonable results.
Tested today for temperature on the simplest possible plant.
The actuator
The first test in P mode only, maintained a steady difference wrt the setpoint. A second test now in PI mode, added a bit of I. Results below.
Since the details and values had been changing until yesterday, I intend to show a tidy schematic maybe during the next week.
I feel good today. Yes!!
