Abstract
Description
technical field
[0001] The invention relates to the technical field of spacecraft attitude dynamics and control.
[0002] SGCMG: Single Gimbal Control Moment Gyroscopes. Single frame moment gyroscope ( figure 1 ). It consists of a high-speed rotating flywheel, a frame supporting the flywheel, and a motor that drives the frame to rotate. Generally, the rotational speed of the flywheel is a certain value, and the control is realized by selecting the rotational speed of the frame drive motor. In other words, the problem of designing the SGCMG control law is actually the problem of choosing a reasonable frame speed. Background technique:
[0003] The large-angle attitude control of the spacecraft is the key to the spacecraft's completion of specific missions. Its control accuracy and speed directly affect the completion of spacecraft application tasks. Since the 1970s, some high-precision large-scale spacecraft in the United States and Russia (Soviet Union) (such as: the s...
