Hey guys,
yesterday I installed the 35 W heater from 3dsolex that I bought a while back, so now I need to adjust the PID values. I tried the following command using pronterface:
This cycles the PID autotune 8 times and outputs the results. The PID values were pretty close each time, so I 'eyeballed' average values of P10, I0.75 and D32. I then set them using:
However, when I then set the temperature to e.g. 200, it overshoots a lot (up to 230 ish). It then cools down to 190 or so and then it settles pretty well. This would work, but imo there should be better values. When finely tuned there should not be any overshoot. Any advice on how to find these values? (I did take a course on systems and control, but that was a long time ago...)
