Integrated guidance and control design for guided bomb with terminal angle constraint

Integrated guidance and control laws have the potential to improve the overall performance of missile systems by taking advantage of the synergism existing between the subsystems. This paper examines the proposed integrated guidance and control by using θ - D suboptimal method to the engagement of ground-fixed target. First, the basic longitudinal mathematical integrated guidance and control model is established. next, a new suboptimal control method, called θ - D, is employed to obtain an approximate closed form solution to this integrated guidance and control problem based on approximations to the Hamilton-Jacobi-Bellman equation. Finally, the performance of designed algorithm is verified via numerical simulation, which shows the feasibility and realizability of the proposed method.
