The Influence and Optimization Design of Transmission Ratio on the Performances of Gimbal Servo-system in CMG
The transmission ratio of the transmission mechanism will affect its efficiency, mass and size, and the performances of gimbal motor in control moment gyro (CMG) for stabilization of spacecraft attitude. In this paper, the transmission ratio of transmission mechanism is optimized for achieving the minimum of the peak output torque of gimbal motor minimum. The relationship curve between the peak output torque of gimbal motor and transmission ratio is given in the gimbal servo-system. The influences of transmission ratio on the rated power of gimbal motor and angle velocity precision of the gimbal servo-system are also analyzed in this paper. The methods and analysis results in this paper can increase the design efficiency and quality, and have the important practical application in design of control moment gyro system and its components.
