This study discusses spacecraft rotational motion in three dimensions. To enhance the reliability of attitude control system, this paper introduces a three-thruster configuration as a minimum unit for attitude control. Since three-thruster configuration cannot generate three independent control torques around three principal axes of spacecraft, proper three-thruster configurations are discussed. Then, by combining Polhode motion and nonholonomic control, this paper introduces some control strategies for the three-thruster configuration to control the angular velocity and attitude motions. Finally, numerical simulations show the validity of the control strategies.
