Spacecraft Line-of-Sight Control Using a Single Variable-Speed Control Moment Gyro
Complete attitude control of a spacecraft is not possible with only one single-gimbal variable-speed control moment gyro due to the conservation of angular momentum. However, partial attitude control without violating the angular momentum conservation principle is still possible. In this paper feedback controllers using only one singlegimbal variable-speed controlmoment gyro are presented that ...
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 Attitude Control Using Control Moment Gyro Reconfiguration
The orientation of a satellite in space described relative to some other object or system is known as the attitude of the satellite. The attitude may be changing with time. To be able to control the attitude of the satellite, it must be equipped with actuators that can produce the required torque. Control Moment Gyroscope is a space craft control actuator which acts as torque amplifier. It is s...
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 کاملIAA-AAS-DyCoSS2-14 -07-06 ATTITUDE CONTROL OF A SPACECRAFT WITH A DOUBLE-GIMBAL VARIABLE-SPEED CONTROL MOMENT GYRO VIA LPV CONTROL THEORY
In this paper, we analyze dynamics of a DGVSCMG(Double-Gimbal VariableSpeed Control Moment Gyro) and develop an easy-to-use LPV (Linear ParameterVarying) model, in which we deal with 3-axis attitude control of a spacecraft equipped with a DGVSCMG. Although it is hard to consider overall stability and control performance of attitude control at the same time with conventional methods, this paper ...
