Problems solved by technology

The traditional jet mechanism can provide a large pulse torque to quickly control the satellite attitude, but it is easy to excite the vibration of the satellite, it is difficult to perform high-precision pointing, and the jet actuator consumes working fluid, so it is not suitable for long-term work
The traditional control torque gyro can overcome the shortage of jet actuators and perform rapid and continuous maneuvers, but affected by friction, the output torque resolution is limited, and high-precision control is difficult

Description

technical field [0001] The invention relates to the field of space vehicle control, and more specifically relates to a compound axis control moment gyroscope. Background technique [0002] The attitude control system is a key component of various space vehicles (such as satellites, deep space probes, etc.), which directly determines the quality of space missions. For the rapid stability and high-precision pointing requirements of the satellite, it is necessary for the actuator to provide large-scale, high-precision, and continuous control torque. The traditional jet mechanism can provide a large pulse torque to quickly control the satellite attitude, but it is easy to excite the vibration of the satellite, it is difficult to perform high-precision pointing, and the jet actuator consumes working fluid, which is not suitable for long-term work. The traditional control torque gyroscope can overcome the shortage of jet actuators and perform rapid and continuous maneuvers, but d...
