中文摘要:
      本文建立了陀螺飞轮的多体动力学模型,用于精确描述其动力学现象。基于简化的多体动力学方程,建立了陀螺飞轮转子两维摆角对力矩器及壳体角速度的传递函数。以此为基础设计了陀螺飞轮转子两维摆角伺服控制系统。仿真结果表明:该控制系统在时变参数条件下能够实现高速转子两维摆角解耦及稳定控制,对实现陀螺飞轮闭环控制具有重要意义。
English Summary:
      This paper established a multi-body dynamic model of the gyrowheel for an accurate description of its dynamic phenomena. The transfer function of rotor’s two-dimensional swing angle of the gyrowheel for the torquer and the angular velocity of the shell is created according to the simplified dynamic multi-body equations. The transfer function can be used to design the servo control system of rotor’s two-dimensional swing angle. It is demonstrated with simulation result that the control system can implement the decoupling of high speed rotor’s two-dimensional swing angle and stably controlling. It is meaningful for the closed loop of the gyrowheel.
