Aiming at the STT spacecraft object with attack angle constraint, an integrated robust design method of three-dimensional guidance control is proposed.Firstly, based on some feasible simplification principles, a nonlinear mathematical model for three-dimensional guidance control integrated design is derived. Then , A kind of robust dynamic inverse design method is proposed for a class of multivariable nonlinear systems by introducing control compensation term. The design of integrated guidance robust control algorithm is completed by combining robust dynamic inverse and dynamic surface control. The simulation results show that the proposed three-dimensional guidance control integrated algorithm can ensure the stable flight and precise guidance of the aircraft and satisfy the constraint requirements of the attack angle.In addition, this scheme possesses strong robustness against parameter uncertainty and equivalent interference .
