Outline of Final Research Achievements |
A control moment gyro (CMG) has become a popular device for an attitude control of spacecraft. A CMG with 2 gimbals and a variable-speed wheel has 3 degrees of freedom and therefore can control 3-degree-of-freedom spacecraft attitude. In this study, attitude control and rate-damping control of a spacecraft by using this type of CMG are proposed. The control algorithm in a singular state of the CMG is also proposed and its validity is examined by ground experiments as well as numerical simulations.
