This paper focuses on robust optimal adaptive control strategy to deal with tracking problem of a quadrotor unmanned aerial vehicle (UAV) in presence of parametric uncertainties, actuator amplitude ...

At least four quadrotor FPV drones can be launched during the attack, each carrying its own warhead. And a langar at the back appears to be for mines; a subtle yet potent new capability. The pace of ...

Using an inner-outer loop design, this paper discusses an attitude and altitude controller for a quadrotor. As a highly nonlinear system, quadrotor dynamics can be simplified by assuming several ...

Therefore, the rotor located at 1.5 m of the wing is the best position, which can not only provide the maximum lift-drag ratio, but also avoid the loss of aircraft performance during the tilt process.

is named Roller-Quadrotor, a rotary-wing aircraft that can fly and hover above the ground. The vehicle is based on a unicycle’s structure; therefore, it can roll on the ground on numerous ...
