A PD nonlinear dynamic inverse guidance law finite time convergence is proposed for the problem of UAV's collision avoidance in this paper. First, a proportional-derivative nonlinear dynamic inverse guidance law, which can be applied to multiple initial angles and speeds, is designed to ensure the security of UAV's collision avoidance. In addition, the stability of guidance law is proved by the circle...
An improved nonlinear dynamic inverse guidance law is proposed for the problem of UAVs collision avoidance in this paper. First, a method based on collision cone boundary is investigated for collision detection. Second, an improved nonlinear dynamic inverse guidance law, which can be applied to multiple initial angles and speeds, is designed to ensure the security of UAVs collision avoidance. In addition,...
Canard Rotor/Wing (CRW) Unmanned Aerial Vehicle (UAV) combines advantages of a helicopter for taking-off and hover, and a fixed-wing aircraft for high speed cruise. A key technology involved is control system design for transition flight. This paper describes flight characteristic of CRW UAV with achieving transition flight from helicopter mode to fixed-wing mode. Dynamic model is built and analyzed...
