Integrated guidance and control of advanced interceptors using second order sliding modes

The enabling guidance and control technology for advanced interceptors to achieve the hit-to-kill accuracy against targets performing evasive maneuvers including spiraling motion is developed on the basis of one unified theory for the purpose of design and analysis, using high (second) order sliding mode control (HOSM). The integration of guidance and flight control systems is achieved in a two-loop guidance and flight control system designed in the combined state space of engagement kinematics and vehicle dynamics. The designed guidance-control system performance is verified via computer simulations using miniature hypervelocity kinetic energy endo-atmospheric interceptor planar model.
