Thermal Comfort Control of an Advanced Space Suit 2001-01-2268
This paper proposes an optimal control strategy for thermal comfort control of an advanced space suit. During an extravehicular activity (EVA), the astronaut's metabolic rate is time-varying depending on the working load, which would prescribe different reference skin temperatures. The purpose of thermal comfort control is to control the skin temperature to the reference value at a certain metabolic rate via a liquid cooling garment (LCG) for astronaut comfort. MPC is expected to achieve the control with the minimum consumable energy. After developing an operational definition of comfort, the structure of the controller and preliminary results are reported.
