Abstract

The present paper studies the properties of observability and controllability using Bond Graph (BG) approach. It is especially applied to a pseudo BG model that describes the thermal transfers in a household refrigerator compartment exposed to an outdoor natural cold airflow. This latter is spread out in an installation, which consists of a cavity covering the side wall of the appliance and connected to inlet and outlet ducts through two openings. The study results show that the pseudo BG model is observable and controllable in time-varying (TV) systems using the concept of duality.
