摘　　要： 研究了平行构型双框架控制力矩陀螺(DGCMG)的操纵律。分析平行构型DGCMG系统奇异情况及控制特点,在此基础上给出角分布操纵律的设计思想及具体形式。从解决奇异问题等方面,对其性能进行分析。针对无法逃离奇异的不足和角分布运动的权重系数动态变化的需要,改进其外框架角速率指令并仿真验证改进后性能。 This paper examines the steering law for parallel mounted double-gimbaled control moment gyro（DGCMG） system. Firstly, singularity problem of parallel mounted DGCMG. System is considered, and the characters of DGCMG system is analyzed by the way of control theory. Secondly, the design idea and content of the angle-distributed steering law is given. Then its performance such as singularity was analyzed. At last, due to the disadvantage that the singularities can＇ t be escaped from and the need that the angle distribution changes dynamically, outer gimbal rate command was improved and simulated.
