%X We propose a robust reconfigurable tracking control scheme for the multi-variable and unstable attitude system of the near-space vehicle (NSV) with parameter uncertainties, external disturbances, dynamic actuator and input constraints. A second-order sliding-mode disturbance observer is used to reconstruct compound disturbances in the loops of attitude and angular rate respectively. The backstepping method with integral filter is used to avoid the growing of differential orders in controller design. The robust terms offset the impact of the reconstruction errors on system performances. By considering actuator dynamics, input constraints and jammed faults, we propose an online linear-matrix-inequality (LMI) optimization distribution algorithm for tracking desired guidance commands. Simulation results show good tracking control performances of the proposed method.
