基于奇异值分解的单框架变速控制力矩陀螺角动量管理方法
An Angular Momentum Management Method of Variable Speed Control Moment Gyroscope Based on Singular Value Decomposition
摘要
Abstract
A new angular momentum management method for variable speed control moment gyroscope (VSCMGs) is proposed in this paper.The control torque (CMGs) mode and the flywheel mode from the VSCMGs is seperated,and the singular value decomposition on the CMGs mode torque output is performed.Only when the CMGs mode is close to singular,the command torque in the singular direction be distributed to RWs mode,so as to make full use of VSCMGs execution ability while ensuring VSCMGs output accuracy.At the same time,zero motion is also introduced into the angular momentum management algorithm to achieve rotor wheel speed balance and frame structure avoidance singularity,and the nonlinearity of the dead-zone of the frame angular velocity and the compensation of neglected items are considered.Simulation results show that the designed control law can achieve high-precision high-torque output when maneuvering large-angle and high-speed spacecraft.关键词
