FLIGHT PATH CONTROL FOR UNMANNED AERIAL VEHICLE

Nasruldeen . A. Almaeyoufi

Abstract :

Planning UAV missions is a difficult problem<o:p></o:p> due a host of real-world complexities, including<o:p></o:p> the presence of vehicle constraints, poorly known<o:p></o:p> obstacle locations, and dynamic information up-<o:p></o:p> dates  that  require  re-planning.  In  addition,  these<o:p></o:p> sophisticated  optimization  problems  must  be sol-<o:p></o:p> ved efficiently for them to be of any use in real-ti-<o:p></o:p> me planning. Fig. 1 – illustrates a simple abstract<o:p></o:p> UAV mission. In this mission, we have 3 points<o:p></o:p> (A, B, C) which represent the flight path for UAV.<o:p></o:p> The flight path of the above mission is divided<o:p></o:p> into 3 sections: <span style="font-size:11.0pt;line-height:107%;font-family:"Calii","sans-serif";
