The spacecraft in orbit resources are severely limited, including computing resources, hardware resources, and energy resources. In this paper, the evaluation of reconfigurability and the autonomous reconfiguration strategy for attitude control system of spacecraft are studied based on the operator theory. Firstly, based on the operator theory of Stable Kernel Representation (SKR) and Stable Image Representation (SIR), the evaluation index of system reconfigurability is given, and the ability of system reconfigurability is described quantitatively. The theory breaks through the limitation of the evaluation method of system reconfigurability based on the theory of coprime decomposition to the linear property of system. At the same time, based on the above results, the maximum boundary of system reconfigurability is given, which provides a clear index for designers to design autonomous reconfiguration strategies. Then, by considering the system reconfigurability in the design stage, the system reconfigurability potential is fully exploited and utilized, providing theoretical guidance for the design of autonomous reconfiguration strategy. Finally, the validity and correctness of the proposed method are verified by a simulation example.
