Finite-Horizon Robust Integrated Guidance-Control of A Moving-Mass Actuated Kinetic Warhead

A game-theoretic approach to the design of robust integrated guidance-control system for a moving-mass actuated kinetic warhead is presented. Feedback linearized form of the kinetic warhead dynamics and a high-order target model are used in the formulation. Nonlinear feedback solution to the robust finite-horizon target interception problem is derived using the recently developed multi-stepping algorithm. Due to its computational efficiency, the multi-stepping algorithm is suitable for real-time implementation. Interception of targets in the presence of modeling uncertainties is demonstrated in nonlinear engagement simulations.
