This project was done as part of my Engineering Controls class. The goal was to regulate a desired reference temperature inside a box using a closed-loop feedback PID controller. A disturbance was introduced in the form of a desk lamp light bulb and was to be rejected by a PC fan blowing in ambient air.
It was important to use a heat source (light bulb) powerful enough to raise the temperature within the box quickly and a fan that would neither under or over-actuate the system. If the fan is to big or too small the system will not be able to track a set point temperature well.
