Control System for a Thermoelectric Cooler in Matlab & Simulink

I'm looking to model the control system block diagram for a thermoelectric cooler (TEC), that will be used in a small fridge. I've used the "Control Systems" toolbox to create block diagrams and get transient and steady state responses before for classes, however the transfer functions were often given or easy to solve. In this case, I'm stuck at finding the transfer function of the TEC, and how to incorporate it into a system. I recently learned about the simscape electronics toolbox that has a TEC block available, and a tutorial on how to use it, however I am unsure of how (or if) that would work with the control systems toolbox.

For some additional information on what I'm trying to acheive, here is an application note on a similar project. I'm mostly trying to recreate Figure 2 from Maxim Integrated's APPLICATION NOTE 5424. I haven't picked out exact components yet.

I'm new to control systems, matlab, simulink, and TECs, so any information would be greatly appreciated! And if I am going about this all wrong, a new direction would be appreciated as well.

Hi @Nicholas Zanon

Since you have found the use of Peltier Device as a Thermoelectric Cooler, then try connecting a controller to it.

I prefer to describe the dynamical system in a bunch of math differential equations because it allows me to visually identify the structure of the input that is suitable to be fed into the system, and obtain the desired system response.
