This paper concerns with the autonomous flight control system of an unmanned helicopter, which is combined with reinforcement learning based neuro-controller. We assume that PID (proportional-integral-derivative) type, linear feedback controller is predesigned and it can stabilize the system with limited performance. The conservative control behavior is improved by the synthesis of the poor feedback...
A blended wing body (BWB) UAV has several aerodynamic advantages of lower wetted area to volume ratio and lower interference drag as compared to conventional type UAV. This paper is focused on the design of the autonomous flight control system for a BWB UAV. An onboard control system is developed by using a powerful computer, navigation sensors and communication modem. The autopilot of the BWB UAV...
The momentum transfer control of a rigid spacecraft with two momentum wheel actuators is investigated using feedback linearization technique focusing on very small nutation angle as a performance index. The equations of motion are transformed to a general linearized form by feedback linearization, including a guarantee of internal dynamics stability. It is known that the configuration of inertia properties...
In this paper, a ducted fan Uninhabited Aerial Vehicle(UAV), being capable of vertical take-off and landing, is studied to understand characteristics and control of the vehicle. The ducted fan UAV is unstable and susceptible to wind due to its external structural shape. Also the ducted fan UAV must change the attitude to gain speed, so it has different characteristics with respect to velocity. To...
