摘　　要：设计了一种平行构型双框架磁悬浮变速控制力矩陀螺(VSDGCMG)操纵律。建立了VSDGCMG动力学模型,提出奇异测度函数,由框架控制目标函数获得框架角速率指令,内转子控制目标函数获得内转子角加速度指令,设计了避开VSDGCMG奇异构型的操纵律。仿真结果验证了两VSDGCMS采用该操纵律能有效跟踪姿态控制指令力矩。A new steering laws for parallel mounted variable speed double gimbal magnetically suspended control moment gyroscopes（VSDGCMG）were designed in this paper.The dynamics model of VSDGCMG was established.The singular measure function was put forward.The steering laws were established through the gimbal control object function which was obtained by gimbal angular rate and flywheel rotor control object function which was obtained by flywheel rotor angular acceleration.The simulation results validated that the VSDGCM using the new steering laws could track the attitude control moment order effectively.
