| Abstract |
Proportional navigation guidance is widely used for zero miss distance in the terminal flight phase of unmanned aerial vehicles(UAVs). However, when line of sight(LOS) error between vehicle and target is large due to accumulating path error from initial and mid-course flight phases, miss distance of proportional navigation guidance(PNG) is significantly increased. This paper presents a dual mode guidance that deals with large LOS error of UAVs. The dual mode guidance is composed of attitude control and acceleration control unlike acceleration control that most research work uses. Furthermore, we propose a switching range changing from attitude control to acceleration control. The switching range of the dual mode guidance is analytically derived with optimality. The proposed scheme is validated by numerical simulations. |
