Integrated guidance and control with terminal angle constraint

Integrated guidance and control laws have the potential to improve the overall performance of missile systems by taking advantage of the synergism existing between the subsystems. This paper examines the proposed integrated guidance and control by using sliding-mode and back-stepping method to the engagement of ground-fixed targets. Firstly, the basic longitudinal mathematical integrated guidance and control model is established. Secondly, in order to deal with the unmatched uncertainly and terminal angle constraint, an integrated guidance and control algorithm is put forward by adopting sliding-mode and back-stepping control design method. At last, the performance of designed algorithm is verified via numerical simulation, which shows the feasibility and robustness of the proposed method.
