Measuring Natural Frequency of Large Control Moment Gyroscope

Abstract:

As an actuator of spacecraft attitude control, the large control moment gyroscope (CMG) produces significant output torque and exhibits excellent linearity features for control, anti-disturbance, and rapid response functions. The large CMG is globally preferred for the execution mechanism of long-life spacecraft. This gyroscope is characterized by massive moving parts and distinct natural frequency between working and halting modes. Based on these features, this study measures the natural frequency of the large CMG by using both hammering and CMG startup testing.
