This paper proposes a task assignment based on auction algorithm for a decoy mission using multiple UAVs which can hover against anti-ship missiles. An optimal deployment direction of decoys are also decided based on the cost function that is calculated with the expected signal power of a seeker and decoy, the distance between them, and fuel availability of the decoys. A simple kinematics is considered to generate two-dimensional motions of anti-ship missiles and a target ship. Numerical simulations are conducted under a visualization environment and validate the performance of the proposed algorithm. A parametric study is also conducted for the decoy mission with multiple missiles and decoys. Lastly, non-linear simulations for ducted fan Unmanned Aerial vehicles (UAVs) are performed to evaluate the feasibility of the proposed high-level task assignment comment for the decoy mission.

This study describes the depth and straight motion control performance depending on control surface combinations of a supercavitating underwater vehicle. When an underwater vehicle experiences supercavitation, friction resistance can be minimized, thus achieving the effect of super-high-speed driving. Six degrees of freedom modeling of the underwater vehicle are performed and the guidance and control loops are designed with not only a cavitator and an elevator, but also a rudder and a differential elevator to improve the stability of the roll and yaw axis. The control performance based on the combination of control surfaces is analyzed by the root-mean-square error for keeping depth and straight motion.
