| Abstract: | An improved constrained (IC) steering law for single gimbal control moment gyros (SGCMGs) with deformed pyramid configuration (DPC) is proposed. First of all, the original system with five pyramid configuration (FPC) whose two adjacent gyros are in failure state is reconfigured as a degraded system with DPC. Then, the singular angular momentum hypersurfaces of the original and the degraded systems are plotted via the singular angular momentum equation of SGCMGs. Based on singular surfaces, the differences b... |
