This paper proposes an energy-optimal guidance law for DACS-equipped interceptors. It explicitly minimizes control usage while ensuring finite-time convergence. Using a partial closed-form solution for aerodynamics, the method achieves high-fidelity prediction with minimal computational load. This offers a practical, fuel-efficient solution for real-time onboard missile defense systems.
