The proportional–integral–derivative (PID) control is the most common control approach
used in industrial and commercial mechatronics products. The PID control has been relevant …

The quadrotor is an ideal platform for testing control strategies because of its non-linearity
and under-actuated configuration, allowing researchers to evaluate and verify control …

In this study, the fully-actuated dynamic equation of quad-rotor as a type of Unmanned Aerial
Vehicles (UAVs) is considered in the existence of input-delay, model uncertainty and wind …

In this paper, a 6-Degrees-of-Freedom (6-DOF) Unmanned Aerial Vehicle (UAV) system with
external disturbance corresponding to sensor failure is considered. The control method is …

In this paper, a cascade PID feedback control algorithm is proposed to stabilize the attitude
of a quadcopter so that the balancing state can be ensured in spite of disturbances. A …

The attitude control of a quadrotor is a fundamental problem, which has a pivotal role in a
quadrotor stabilization and control. What makes this problem more challenging is the …

A quadcopter is a type of Unmanned Aerial Vehicles (UAV) with four propellers and ability to
take-off/landing in limited space. In the past few years, quadcopters have become an …

This paper proposes a novel finite-time backstepping framework combined with an auxiliary
input-saturation compensator and applies it to tackle the trajectory tracking problem of …

An attitude control strategy based on Ziegler‐Nichols rules for tuning PD (proportional‐
derivative) parameters of quadrotor helicopters is presented to solve the problem that …

This paper describes nonlinear dynamics model of x-configuration quadrotor using Newton-
Euler modelling technique. To stabilize quadrotor attitude (roll (ϕ), pitch (θ), yaw (ψ)) during …
