| 摘 要： | 用角动量超曲面仿真分析了控制力矩陀螺构型奇异的产生机理。基于控制力矩陀螺群动力学总角动量和输出控制力矩,讨论了典型构型奇异存在的状况,并确定了奇异点存在的判断依据,对五棱锥构型的显奇异和隐奇异进行了角动量超曲面仿真,发现能通过零运动脱离奇异状态的隐奇异点,为控制力矩陀螺群的操纵律设计提供了重要依据。控制系统数学仿真结果表明该分析法有效。

| Abstract: | The mechanism of making singular for single gimbal control moment gyros（SGCMGs） configuration was analyzed by angular momentum hypersurface simulation in this paper.Several typical cases were discussed based on SGCMGs dynamics angular momentum and control torque output.The judgment rule of singular and simulate the angular momentum hypersurface for FPC was determined.The hiding singular point of getting rid of singular station by zero motion could be found by the simulation,which would provide one important basis for designing of SGCMGs steering law.The simulation results of some control system showed that this method was effective. |
