Development of electronic controls for refrigerators based on the supervisory control theory

This paper presents an application of the supervisory control theory in the development of control logics for refrigerators. A structure containing a Peltier Mini-Refrigerator controlled by an electronic circuit was developed, aiming to create and validate different control strategies that will be implemented in household and commercial refrigerators. The local modular control approach is applied in the supervisor synthesis, bypassing computational restrictions found in the monolithic approach. An implementation framework is proposed and some experimental results are obtained.
