A quadcopter is underactuated where there are 6° of motion with only four rotors to control
all six motions. Varying the speed of the four rotors can produce thrust, roll, pitch and yaw …

In this study, an energy efficiency study has been carried out through the moment values of a
quadrotor applied in the position control with the differential evolution algorithm (DE), which …

In today's automation control systems, the PID controller, as a core technology, is widely
used to maintain the system output near the set value. However, in some complex control …

In recent years, multi-rotor UAVs have become valuable tools in several productive fields,
from entertainment to agriculture and security. However, during their flight trajectory, they …

Abstract Unmanned Aerial Vehicle (UAV), specifically a quadcopter is publicly popular
which it provides services in different applications such as aerial delivery, aerial …

A quadcopter is an underactuated and nonlinear system which requires a robust controller
to aid in maneuvering the quadcopter during flight. A Proportional-Integral-Derivative (PID) …

In recent years, the scientific community has shown considerable interest in airborne
hovering vehicles in general and autonomous flying vehicles in particular. The most …

In this paper, we propose a cascade control system design based on linear active
disturbance rejection control (SMC&A-LADRC) to address the following quadrotor UAV …

In the context of digital manufacturing and intelligent manufacturing systems, optimizing the
inverse kinematics (IK) of manipulators is crucial for improving manufacturing efficiency and …

Objectives The ratio of failures in avionics caused by vibration is considerably high.
Reducing the impact of vibrations on the performance of equipment performance is critical …
