Abstract

Based on singular value decomposition (SVD) theory, the mechanism of escaping/avoiding singularity using generalized singularity-robust (GSR) steering law and weighted singularity-robust (WSR) steering law is analyzed for a spacecraft, which uses single gimbal control moment gyros (SGCMGs) as the actuators for attitude control system. Then the expression of output-torque error is given at the point of singularity and the error's inescapability is proved also. How to reduce and use the output-torque error is discussed and the corresponding steering law is designed. Simulation results show that the proposed steering law can escape both internal and saturation singularities effectively, and the output-torque error can be bounded too.
