A Decomposition Control of Variable Speed Control Torque Gyro

Abstract IPACS (energy / attitude control integrated control system) is the main problem studied in recent years. In view of this problem, on the basis of the existing flywheel control law torque analysis, the singular value decomposition of torque output in CMGs mode is carried out. Only when the CMGs mode is close to singular, the instruction torque in the singular direction will be allocated to RWs so as to give full play to the VSCMGs execution ability under the premise of ensuring the output accuracy of the VSCMGs. In order to realize the control better, the zero motion control law and robust pseudo-inverse operation rate are analyzed.
