With an increase of UAVs in logistics and transportation, the safety of UAVs operated in the
urban wind environment becomes an important issue. Small UAVs are more sensitive to the …

Energy beam machining is a type of micro/nano-manufacturing technology for advanced
materials. The energy beam is composed of the matter which exhibits not only particle but …

Unmanned aerial vehicles (UAVs) are widely used, particularly in urban environments.
However, existing studies on multi-rotor UAVs have rarely attempted simulations or …

Disturbance observer-based control is widely employed in control systems. It demonstrates
the ability to estimate intricate disturbances for subsequent measurement, thereby enabling …

The study proposes a precise method for modeling and verifying quadrotor unmanned aerial
vehicles (UAVs) using aerodynamic data from wind-tunnel tests. The dynamic model often …

The paper proposes a precise method to measure the angular acceleration of a quadrotor
Unmanned Aerial Vehicle (UAV) using multiple accelerometers. The method estimates the …

In this study, a new method was developed to extend the flight distance of unmanned aerial
vehicles such as quadcopters that operate on a limited battery capacity. The suggested …

As of today, unmanned aerial vehicles (UAVs) are used in many fields such as courier
service, reconnaissance surveillance, and aerial photographing. According to such trend …
