Design of a Temperature Controller for an Oven

This paper describes the design and implementation of an automatic temperature control system. The developed temperature controller is designed to control temperature in an oven. The temperature can be controlled manually or automatically with a temperature profile imposed by the user. A bi-positional controller is implemented for temperature control. In manual mode, the user will select the set-point and the upper and lower limits. The control system will maintain the temperature within the prescribed limits. In automatic mode, the user can select a temperature profile, and the control system will impose that the temperature follows the prescribed temperature profile.
