The coupling between electrical and thermal systems within the space station Freedom

The dynamic coupling which exists between the electrical power system and the thermal system of space station Freedom is discussed. Analytical models are derived based on the principle of conservation of energy and the controller action, which tries to maintain a particular temperature set point. An application generator is used for real-time simulation and modeling of the combined system. The model presented here provides a unified approach for global implementation of built-in test as well as local real-time fault detection and isolation for on-orbit operation.<
