摘要：
Aiming at the multiple directional constraints and angular velocity constraints in spacecraft attitude redirection，an improved backstepping control method is proposed. Firstly，the multiple directional constraints are expressed as a quaternion-presented convex constraints set. Based on these，a novel convex potential function with explicit physical meaning is designed to ensure that the attitude direction satisfies the task requirements. Secondly，considering the limitation of angular velocity，a virtual angular velocity command is proposed using the hyperbolic tangent function，which ensures that the angular velocity is always within the constraint range. Further，a barrier Lyapunov function is introduced to limit the angular velocity tracking error. On the basis of these above，the attitude control law is designed using the backstepping method，and the asymptotic stability of the closed-loop system is proved through Lyapunov method. Finally，the effectiveness and superiority of the designed control law are verified by numerical simulation and comparative simulation. © 2023 China Spaceflight Society. All rights reserved.
