“…Paper [ 15 ] has verified the stability of a control system based on control theory using the thermal software tool ESATAN/FHTS. Valenzano et al have taken the gain of a control algorithm as a parameter to verify the stability of the control system of Node 2 and 3, with the dangerous conditions of space stations being predicted [ 16 ]. De Palo S et al have analyzed the stability of the thermal and hydraulic control loop of the Columbus in the ISS by using the theory of automatic control.…”

Scientific experimental racks are an indispensable supporter in space stations for experiments with regard to meeting different temperature and humidity requirements. The diversity of experiments brings enormous challenges to the thermal control system of racks. This paper presents an indirect coupling thermal control single-phase fluid loop system for scientific experimental racks, along with fuzzy incremental control strategies. A dynamic model of the thermal control system is built, and three control strategies for it, with different inputs and outputs, are simulated. A comparison of the calculated results showed that pump speed and outlet temperature of the cold plate branch are, respectively, the best choice for the control variable and controlled variable in the controller. It showed that an indirect coupling thermal control fluid loop system with a fuzzy incremental controller is feasible for the thermal control of scientific experimental racks in space stations.
