Abstract

The invention discloses a small-size speed change control moment gyroscope, and belongs to the technical field of control moment gyroscopes. The small-size speed change control moment gyroscope comprises a high-speed component, a connection bracket and a low-speed component, wherein the high-speed component supplies constant angular momentum in a control moment gyroscope mode and outputs fine moment required by whole satellite attitude control in a flywheel mode; the connection bracket is connected with the high-speed component and the low-speed component and guarantees the orthogonal perpendicularity between the angular momentum direction and the axial direction of a framework; the low-speed component supports the high-speed component and the connection bracket and supplies a mounting interface for a whole satellite; in the control moment gyroscope mode, large moment which is required by fastmoving of the whole satellite and is also orthogonal to the angular momentum direction and the axial direction of the framework is generated; in the flywheel mode, the fine moment output by the high-speed component is transmitted to the whole satellite for the attitude control. The speed change control moment gyroscope disclosed by the invention realizes the high-precision framework locking, the minimization, the light weight and the high rigidity, and is suitable for the application to small quick satellites.

Description

technical field [0001] The invention relates to a small variable-speed control moment gyroscope, which belongs to the field of space actuators. Background technique [0002] Commonly used inertial actuators in spacecraft attitude control systems include flywheels and control moment gyroscopes. The flywheel is an attitude control actuator with variable rotor speed. The output resolution is high but the torque value is small. It is often used for high-precision and stable control of spacecraft attitude; the control moment gyro is to change the angular momentum of the rotor through the rotation of the frame when the rotor speed is constant. The attitude control actuator that outputs torque in the direction of direction, the output resolution is low but the torque magnitude is large, and there is a problem of singularity of the control law. The variable speed control torque gyro is a single-frame control torque gyro with variable rotor speed. The variable speed control torque g...
