Research on the integrated design of unmanned combat aircraft end-of-flight guidance control. The integrated guidance and control system model is established. On this basis, the trajectory linearization control method is used to design the integrated control law. In order to deal with a large number of uncertainties such as perturbation of aerodynamic parameters, measurement error interference and target maneuver, The linear disturbance observer technique estimates and compensates for the uncertainty and proves the stability of the proposed method based on Lyapunov principle. The simulation results show that the integrated guidance control method can effectively improve the control accuracy and guarantee the robustness.
