Attitude Dynamics/Control of Dual-Body Spacecraft with Variable-Speed Control Moment Gyros
The dynamics equations of a spacecraft consisting of two bodies mutually rotating around a common gimbal axis are derived by the use of the Newton–Euler approach. One of the bodies contains a cluster of single-gimbal variable-speed control moment gyros. The equations include all of the inertia terms and are written in a general form, valid for any cluster configurations and any number of actuat...
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 کاملOptimal control for control moment gyros - Center-stable manifold approach
This paper proposes a framework for optimal control of mechanical systems possessing conserved quantities such as control moment gyros (CMGs). It will be shown that output regulation theory is appropriate to handle such constraints and that the center-stable manifold method for solving the associated Hamilton-Jacobi equation is effective for computing the optimal feedback control. With this fra...
متن کاملSpacecraft Adaptive Attitude and Power Tracking with Variable Speed Control Moment Gyroscopes
Control laws for an integrated power/attitude control system (IPACS) for a satellite using variable-speed singlegimbal control moment gyroscopes (VSCMGs) are introduced. Whereas the wheel spin rates of the conventional CMGs are constant, the VSCMGs are allowed to have variable speeds. Therefore, VSCMGs have extra degrees of freedom and can be used to achieve additional objectives, such as energ...
متن کاملAttitude-Tracking Control with Path Planning for Agile Satellite Using Double-Gimbal Control Moment Gyros
In view of the issue of rapid attitude maneuver control of agile satellite, this paper presents an attitude-tracking control algorithm with path planning based on the improved genetic algorithm, adaptive backstepping control as well as sliding mode control. The satellite applies double gimbal control moment gyro as actuator and is subjected to the external disturbance and uncertain inertia prop...
