| May 13, 2019 at 15:56 | comment | added | croc | I need precise temperature control and an on-off gap controller isn't really a good choice IMO. I'll have to do a weighed transition from heating to cooling model (or vice versa) to simulate real world temperature response (because the response isn't instant IRL), but I think this should be good enough for some basic tuning (at least to give me a good base where to start from). | |

Tuning a PI controller for this process should be interesting. Are you sure that you don't want to go with an on-off gap controller, such as what is used to control indoor temperatures in a house? | |

I've updated my question with some data for the cooling model, is that enough? Also, can you explain in your answer how you calculated the q and k values?

| May 9, 2019 at 9:07 | comment | added | Alex Trounev | @croc To build a cooling model, data is needed. | |

Great! This looks almost identical to the step model response that's modeled with the transfer function in Matlab. Can you just update your answer with an explanation of how you calculated the q and k values? Also, could this/such model also be used to simulate cooling of this system (with different q and/or k values probably)?
