Description

technical field [0001] An integrated double-frame magnetic suspension control moment gyro magnetic bearing control system, which is used for high-precision suspension control of the double-frame magnetic suspension control moment gyro rotor, can realize fast and non-interference signal transmission with the frame control system, and control parameters For high-speed data acquisition and online monitoring, and online modification of key variable values, it is suitable for high-precision, highly integrated servo mechanism control systems. Background technique [0002] Control Moment Gyroscope (CMG) is a kind of actuator used for spacecraft attitude control. Compared with traditional attitude control mechanisms such as jet thrusters and momentum wheels, the control moment gyroscope has significant advantages such as large control range, high precision, large output torque, and only needs electric energy to work, so it is used in large spacecraft such as space stations. Double ...
