Abstract:In this paper an autopilot system is designed for cruise mode of a fixed wing unmanned aerial vehicle (UAV). The biggest challenge is to maneuver UAV at lower altitudes while overcoming strong coupling between longitudinal and lateral mode. The six-DoF simulation model of the UAV plant under consideration is a non-linear one, to control it for cruise mode it is trimmed at cruise conditions for decoupling of plant model. The control design is divided into two phase, in first phase PID controllers are designed f… Show more
