Abstract

The invention relates to a self-adaptive compensation method for high-frequency disturbance of a control moment gyroscope frame system. The method is applicable to self-adaptive compensation application of high-frequency moment disturbance with fixed frequency or frequency drift characteristic. The self-adaptive feed-forward compensation method for high-frequency disturbance of the control moment gyroscope frame system provided by the invention can attenuate the dynamic unbalance disturbance frequency amplitude of a rotor to 10% or below under the condition that the response bandwidth of a frame is lower than the frequency of the rotor, so the maximum disturbance factor, namely the dynamic unbalance disturbance of the rotor, in the rotating speed of the current frame is weakened to a great extent. According to the invention, the rotation speed stability of the frame is doubled, and then the stability of the output torque of a control moment gyroscope is doubled.

Description

technical field [0001] The invention relates to an adaptive compensation method for controlling high-frequency disturbance of a moment gyroscope frame system, which is suitable for adaptive compensation application of high-frequency torque disturbance with fixed frequency or frequency drift characteristic. Background technique [0002] As the core attitude control component of large spacecraft and strong maneuvering spacecraft, the control moment gyroscope's output torque stability and accuracy become the decisive factors for the stability and accuracy of the whole star attitude control. The output torque of the control torque gyro is obtained by the cross product of the H vector of the high-speed rotor and the low-speed frame speed, so the disturbance component contained in the frame speed will greatly affect the stability and accuracy of the output torque. The frame speed is affected by multi-source interference, which comes from factors such as angle measurement system, m...
