Hi,

My model uses inputs which constitute measured temperatures. These measured temperatures (of the real system) are samples every 30s which means that the temperature is average over 30s. This however poses some problem since the highest peak temperature and lowest valley temperature are needed (to trigger an on/off controller).

Thus I have to somehow un-average the temperature input signals, i.e. the dT/dt of the sampled signal should be incorporated.
This can probably be done with an PID controller but what values for the P, I and D?
