Research on guidance and control of surface ship by unmanned aerial vehicle

For some kind of unmanned aerial vehicle, the realization of the flight towards warship in the sea depends on its guidance method, flight control method and target tracking method, and most importantly, the reliability of the combination of these methods to form a robust guidance and control system. A proportional guidance method was used to produce the flight commands, PID control method and gradient descent algorithm were used to acquire the attitude of unmanned aerial vehicle to control the flight motion, and the combination of Camshift algorithm and Kalman filter was used to fulfill target tracking. The math model and simulation model of the whole guidance and control system were established. Math simulation and hardware-in-the-loop simulation were implemented to verify the reliability of the combination of the guidance method, the flight control method, the gradient descent algorithm for attitude and the target tracking method.
