Sea-skimming missiles are missiles which fly very close to sea surface. This is to avoid detection by radar or make it difficult for defense systems to intercept the missile. Sea-skimming missiles are expected to descend to the surface of the water to start avoiding detection as early as possible right after the launch. However, this steep descent is a challenging task because of the platform movements, ballistic phase with the booster, and different environmental disturbances. It is also expected that the missile’s descent should be fast without any overshoot because of the sea below. Thus, a robust and rapid descent control system design is one of the main challenges for sea-skimming missiles. This thesis proposes modified proportional-derivative controller with predictive model for calculating the system input for the powered descent to the sea surface, with no or minimum overshoot. The effectiveness of the proposed method is evaluated through extensive simulations and compared against traditional control approaches and guidance methods.
