Singularity avoidance in redundant single gimbal control moment gyroscope systems

  • Single gimbal control moment gyroscope (SGCMG) is one kind of inertial actuators applied to the spacecrafts. Three or more SGCMGs are used in order to meet the need of the 3-axis attitude control. Singularity often arises when several SGCMGs work coordinately. A new detecting method of avoidability of singular states was proposed which was suitable for SGCMG systems. This approach can transform the problem of detecting avoidability/unavoidability to qualitative study on a set of nonlinear ordinary differential equations. Several examples indicate that the method presented above is feasible.
