Abstract

The control accuracy of Single Gimbal Control Moment Gyroscope (SGCMG) is limited by the existence of interference factors such as dynamic imbalances. This paper analyzes the output torque disturbance of SGCMG from a dynamic perspective and verifies the influence weights of disturbance factors through simulations, providing a reference for the control of torque output stability in SGCMG. Firstly, considering factors such as static and dynamic imbalance, installation errors of the high-speed rotor system using the Newton-Euler method, a preliminary analysis of each subsystem is conducted. Secondly, considering disturbance factors such as frame speed, a dynamic model analysis is performed. Finally, based on actual parameter values, the characteristics of the system's output torque are analyzed through simulations. Experimental results show that the torque output process of the system is stable under ideal conditions. However, in the presence of disturbances such as dynamic imbalance, the stability of SGCMG's torque output process is influenced to varying degrees. The analysis of the influence weights of various disturbance factors is accomplished using principal component analysis.
