Research on adaptive and differentiated control method of drive controller in Wentian and Mengtian experimental cabin of space station

Abstract

Focused on the key single machine of the Alpha sun orientation subsystem in the power sub-system of the Wentian and Mengtian experimental cabin of the space station - the in-cabin and extra-vehicle drive controller which needed to autonomously complete the cabin segment (Wentian, Mengtian) and cabin space (inside and outside the cabin) identification and independently fulfill the needs of the differentiated control of flexible sailboards in the Wentian and Mengtian experimental cabins by receiving the commands of the space station digital management sub-system and the GNC sub-system according to the requirements of the space station’s energy assurance tasks, this paper proposed an in-cabin and extra-cabin drive controller autonomous identification and differentiated control method. At the same time, combined with the different working modes inside and outside the cabin, the drive controller executed the information collection and processing of other functional components in the Alpha sun orientation subsystem, and completed the closed-loop control and fault detection processing of the Alpha sun orientation device, and sent the different processing information to the GNC sub-system and digital tube sub-system. As a key single machine of the power supply subsystem which was a key sub-system of China’s space station, an important national project, the in-cabin and out-cabin drive controller was very important to ensure the energy security of the entire space station.
