Description

technical field

[0001] The invention relates to a fault-tolerant system of a magnetic levitation control moment gyro high-speed rotor inverter, which is used for the fault-tolerant control of a permanent magnet brushless DC motor with a small armature inductance, and is especially suitable for the high reliability of the driving parts of the attitude control actuators of satellites and space stations. control. Background technique

[0002] Space applications require high precision, high torque, low power consumption, high reliability and long life for attitude control actuators. The magnetic levitation control moment gyroscope has the advantages of no friction and wear, no lubrication, long life, and high precision through active vibration control because its high-speed rotor is supported by magnetic levitation. It is an important attitude control actuator on the spacecraft. The high-speed rotor of the magnetic levitation control torque gyro is driven by a brushless DC moto...
