PID simulator without feedback

[SMARDT_CHILLER]

Hello,

I started making up some PID simulator, see attached. For the plant response its a ln function. So this gets the oscillations right if you crank up delay and/or gain. But at the moment there is no actual feedback from the PID. So it oscillates around setpoint and PID response would more or less oscillate.

Its not the most pretty thing, but its more a draft.

Any help, how I could implement the feedback from the PID? Multiply PID output by some factor and add it to the plant output?

Thanks!

It is imperative to wire the dt (s) input in order to make PID working. PID are time dependent.

Read the documentation of the PID to understand how to call it.
