To keep the attitude control of maneuvering reentry vehicle in reentry phase, the strict feedback attitude model of reentry vehicle with time-varying parameters is built. An adaptive robust controller is designed based on backstepping, which consists of backstepping adaptive control and robust control. The controller design method uses adaptive strategies to estimate the unknown parameters, introduces robust control to avoid the singularity in parameters estimation of gain matrix phase. Theoretical analysis shows that all signals of the closed-loop system are proved intimately uniform bounded. Simulation results of six-degree-of-freedom demonstrate that the proposed control method has strong robust performance.
