  This paper introduces a feedback-based temperature controller design for
intelligent regulation of food internal temperature inside of standard
convection ovens. Typical convection ovens employ an open-loop control system
that requires a person to estimate the amount of time needed to cook foods in
order to achieve desired internal temperatures. This approach, however, can
result in undesired results with the final food temperatures being too high or
too low due to the inherent difficulty in accurately predicting required
cooking times without continuously measuring internal states and accounting for
noise in the system. By implementing and introducing a feedback controller with
a full-order Luenberger observer to create a closed-loop system, an oven can be
instrumented to measure and regulate the internal temperatures of food in order
to automatically control oven heat output and confidently achieve desired
results.
