Abstract：As inertial actuators mounted on the spacecraft, single gimbal control moment gyroscope (SGCMG) systems can affect the attitude control accuracy to a great extent. In order to improve the trajectory tracking performance in gimbal angle space for SGCMG systems, an adaptive compensation controller is adopted, which has three terms, i.e., proportional, differential, and adaptive compensation ones. This controller not only can realize finite-time tracking control in gimbal angle space, but also can make the tracking error converge to zero exponentially. Simulation results of a certain pyramid-type 4-SGCMG system indicate that the control algorithm presented above is feasible.
