Abstract
Unmanned Aerial Vehicles (UAV) have recently been used to provide many kinds of services, among them fixed-wing UAVs are advantageous for long flights and wide-area observations. In order to realize wireless relays station by the UAV, the UAV should continue to accurately turn along a predetermined circular path with its radius specified. To realize the path, we propose a new turn path control system that consists of radius deviation control and nose heading angle control on the UAV, and describe simulation results by which it is confirmed that the proposed control system worked well. And finally, we describe results of the flight verification experiment.
