Bilinear System Identification and Temperature Control Law of Insulation and Heat Transport System for Space Using Fluorinated Inactive Liquids

抄録

Miniaturization and high performance are always required for space equipments. But, it can be said that miniaturization and high performance are generally contradictory requirements. In this research, a fluid loop insulation and cooling system was built as a means of realizing both miniaturization and high voltage. For the working fluid of the system, fluorinated inactive liquids were used which can provide high electrical insulation and thermal conductivity. In this paper, to begin with, the electrical insulation property of the fluorinated inactive liquids was verified by an experiment. Then the dynamics model of the constructed insulation and cooling system was derived by a system identification experiment. Finally, a control law for temperature control was constructed using the estimated model and cooling performance of the system was examined by both numerical simulations and experiments.
