Application of MBSE in the Control Design of Control Moment Gyros on Spacecraft

With the advantages of design process visualization and modelization, model-based systems engineering (MBSE) is efficient to solve the problem such as the changeability of design requirement, the difficulty of carrying out verification at early stage. Oriented at the design requirement of spacecraft attitude control mission, the MBSE method is applied in the single gimbal control moment gyros (SGCMGs) control system. Through the process of requirement analysis, schematic design, simulation and verification, we model the SGCMGs control system requirements, establish the control framework, and analyze the interface between the facilities. The application is conducive to the integration and continuation of the relative knowledge and experience on spacecraft attitude control system.
