Modelling of Gimbal Control Moment Gyro and Analysis of Gimbal Disturbance Impact
Original scientific paper Control Moment Gyroscope is one of the main sources of disturbance affecting the accuracy of attitude control system in the spacecraft. This paper concentrates on analysing and testing the micro-vibrations produced by CMG. To analyse its disturbance features systematically, the mechanical features of flywheel, frame and the entire CMG will be firstly studied, and then ...
متن کاملSpacecraft Angular Velocity Stabilization Using A Single-Gimbal Variable Speed Control Moment Gyro
Feedback controllers for the stabilization of the angular velocity vector of a rigid spacecraft using a single-gimbal Variable Speed Control Moment Gyro (VSCMG) are presented. Linearization of the equations of motion show that complete attitude stabilization is not possible via linear methods. Nonetheless, it is shown that the linearized angular velocity equations are controllable, and a simple...
متن کاملSpacecraft Angular Velocity and Line-of-Sight Control Using A Single-Gimbal Variable-Speed Control Moment Gyro
It is well known that complete attitude control of a spacecraft is not possible with only one single-gimbal Variable-Speed Control Moment Gyro (VSCMG) due to the conservation of the angular momentum. However, partial attitude control without violating the angular momentum conservation principle is still possible. In this paper, feedback controllers that stabilize the angular velocity vector of ...
متن کاملAdaptive Control of Double-Gimbal Control-Moment Gyro with Unbalanced Rotor
Adouble-gimbalcontrol-momentgyro (CMG) ismodeled usingLagrange’s equations,and an adaptive feedback control law is developed to follow a commandedCMG motion. The control law does not require knowledge of the mass properties of the CMG. A Lyapunovargument is used to prove that command following is achieved globally with asymptoticconvergence. Numerical simulationsare performed to illustrate the ...
متن کاملPerformance Testing of a Magnetically Suspended Double Gimbal Control Moment Gyro Based on the Single Axis Air Bearing Table
Integrating the advantage of magnetic bearings with a double gimble control moment gyroscope (DGCMG), a magnetically suspended DGCMG (MSDGCMG) is an ideal actuator in high-precision, long life, and rapid maneuver attitude control systems. The work presented here mainly focuses on performance testing of a MSDGCMG independently developed by Beihang University, based on the single axis air bearing...
