PLANT AND CONTROLLER IDENTIFICATION AND DESCRIPTION
For the reflow soldering oven, the heating elements will be the primary plant as this project involves
controlling the heat of the system. If the oven is unable to cool relatively quickly, then the added
fans will be the secondary plants. In place of fans, simply opening the door may suffice for cooling.
For both of these systems, controllers may necessary and the systems will be placed in unity
feedback creating a closed loop system.
A temperature sensor also makes an appearance in the overall system and is integral in the control
process. Lastly, an analog-to-digital converter will be used to convert the sensor readings into digital
data for a computer to process.
