Kontrol Ketinggian Minimal Misil Udara-ke-Permukaan Menggunakan Metode Tembakan Runtun Langsung

This paper describes numerical solutions of air-to-surface missile using a direct multiple shooting. The missile is assumed to attack a fixed target by a vertical dive. The missile guidance problem is reinterpreted using optimal control theory resulting in the formulation of minimum integrated altitude problem. The formulation entails nonlinear, 2-dimensional missile flight dynamics, boundary conditions and state constraints. The influence of the boundary conditions on the structure of the optimal solution and the performance index are investigated. The results are then interpreted from the operational and computational perspective. The optimal trajectory is split it up in 4 sub-intervals: diving, flight on the minimum altitude, climbing and diving
