Simulatable combined feedback loops plus thermal model for the NerdKits Sous Vide Controller.

Try changing H2's transfer function from "10" to "10 + 0.001/s" to add an integral term to the controller and watch how it gets rid of steady-state error! Then, adjust the 0.001 and see how you can make it either oscillate or be largely ineffective.
