Abstract :
The paper deals with the attitude maneuver and attitude tracking for agile small satellites with Single Gimbal Control Gyroscopes (SGCMGs) as actuator. Firstly, the paper presents the dynamic of the spacecraft including the actuator model. To deal with the influence of some uncertainties, an adaptive control system is designed. The stability of the controller is proved by the theory of Lyapunov. Finally, a numerical simulation is given based on an agile small satellite with SGCMGs as actuator, and compared with the method of PID controller. The adaptive control method is better than PID method in attitude maneuver and attitude angular velocity tracking, especially considering model uncertainty and disturbances. The simulation results illustrate the validity of the method in the paper.
