An adaptive integrated guidance and control scheme for a diving hypersonic vehicle with multiple constraints is proposed in this paper. In the proceeding of integrated guidance and control algorithm generation, the input constraints, three-dimensional impact angle constraints, and constraints of Euler angles and body rates are all taken into consideration. The calculating models of aerodynamic force and moment are converted into forms of partial derivative matrix, and the integrated guidance and control strict feedback model is established by combining the flight control dynamics with the engagement kinematics; the pseudo-input law belongs to the flight system is designed based on the variable gain idea and adaptive dynamic surface back-stepping method, and then the final integrated guidance and control law is presented depending on the block dynamic surface back-stepping control approach, the Lyapunov function is built by dynamic surfaces, error vector of the filters and estimation error vector, and finally the states of the closed-loop system are proved to be uniformly ultimate bounded. The numerical simulation results show that the integrated guidance and control law presented in this article can ensure an accuracy interception with the specified impact angle and the states of the vehicle are all stability.
