摘要
Abstract
Aimed to the attitude control of a rigid spacecraft which actuator had two control torques, the attitude control law of the underactuated spacecraft asymptotically stabilized was realized by using switching algorithm and backstepping control according to the condition that whether the underactuated axis was an inertial symmetric axis or not in this paper. The attitude angular velocity stabilization by three attitude maneuvers in accordance with the dynamic model first. The attitude angle stabilization was achieved through five attitude maneuvers based on the dynamic stabilization according to the kinematic model then. The theory analysis and simulation results showed that this control strategy was effective, which could realize the attitude control of the rigid underactuated spacecraft.关键词
