This paper proposes a novel nonlinear control approach for two-axis gimbal to achieve accurate real-time tracking performance in maritime surveillance applications. For this objective, the system must overcome complexities and limitations, including dynamics, coupled Euler angle-based measurements, delay time constraints. The backstepping controller was designed, taking into consideration nonli...

Small robot helicopters are becoming a popular research platform due to the availability of off-the-shelf components and their suitability for useful applications. We describe the Oxford Aerial Tracking System (OATS) that we are commissioning which takes a commercial airframe and low-level flight controller, and adapts these for use in applications requiring the visual tracking of ground target...

Abstract. This work describes a control solution for real time object tracking in images acquired RPAS on an inspection environment. This, controlling 3-axis gimbal mechanism to camera orientation embedded RPAS, using its image processed feedback. The objective of is maintain the target interest at center plane. proposed uses YOLOv3 detection model order detect and determine, thru rotation matr...

Among several usages of unmanned aerial vehicles (UAV), wireless relay systems for high altitudes using fixed-wing UAVs, or high-altitude platform stations (HAPS), are some the most promising applications. To realize by making advantages long flight duration and endurance airplanes, this paper proposes an antenna pointing control system mechanical gimbals onboard a UAV continuously turning mida...

The developed y4 copter is an Unmanned Aerial Vehicle with autonomous subsystems which reports the fully automated y4 copter for the first time. Automation is implemented through maintaining the desired roll, pitch and yaw therefore the flight stability as well as in case of controlling elevation. An improved and efficient algorithm that uses Quaternion is implemented to determine Euler angles ...

In a lidar system an accurate transmitter-receiver alignment is essential for correct results. Usually this optical adjustment is time consuming and requires the intervention of highly qualified personnel. As a solution to this problem, a fast and precise automatic alignment procedure is presented, based on a simple model of the transmitter-receiver overlap. The lidar mounted at the Naples Univ...
