Old-School Analog Temperature Control Circuits Solved with Modern LT spice Thermistor Dynamic Models, Part 2

This temperature profile is one of the principal reasons why we need a PID controller, which will be able to very accurately follow the required dwells and slopes, while also avoiding big oscillations ...
