Attitude control of on-orbit capture spacecraft with angular velocity constraint

Aiming at the attitude control problem of spacecraft in capturing non-cooperative target process, a dual tracking robust adaptive controller is designed. Firstly, bounded virtual angular velocity designed for kinematics equations to guarantee that converges zero quickly. Secondly, new constructed based on barrier Lyapunov function ensure error between and real bounded. The physical constraint satisfied. Applying Lyapunov's stability theory, global asymptotic closed-loop system analyzed. To overcome nonlinear parameter perturbation with unknown upper bound process target, an updating law linear regression operator estimate rotational inertia on-line. Finally, trajectory targets through numerical simulation. simulation results demonstrate algorithm effective under or internal bound.
