I try to do some heater controlling and no matter what I do the DFactor stays zero. The only thing which brings some action is to use a negative D value which brings dampening but on the ramp-up and not when reaching the target value. Long story short: Can't for the live of me damp the overshoot the PI Part is producing and I need an "overdampend" setup because the customer is sort of intolerant concerning overshoot. Also the underlying Formula is sort of weird.
Has anybody any advise or has implemented a working PID with anti windup for Mervis?
