An improved active disturbance rejection control (IADRC) is proposed to stabilize and reject
exogenous disturbances and system uncertainties for a 6-degree of freedom (DOF) …

This paper presents a fixed-time extended state observer-based adaptive sliding mode
controller evaluated in a quadrotor unmanned aerial vehicle subject to severe turbulent wind …

In this article, we introduce a translational force control method with disturbance observer
(DOB)-based force disturbance cancellation for precise 3-D acceleration control of a multi …

In this paper, a Disturbance Observer Based Controller (DOBC) is designed for the
quadrotor. Unmanned aerial vehicle control becomes more challenging because of its cross …

Purpose The hybrid control system of the nonlinear PID (NLPID) controller and improved
active disturbance rejection control (IADRC) are proposed for stabilization purposes for a 6 …

Unmanned Aerial Vehicles (UAVs) have been used extensively in many applications, such
as surveillance, medical transportation and delivery tasks. These applications usually …

In recent years, quadrotor applications have increased because of their simplicity, low cost,
different sizes for different applications, and easy implementation. There are a large variety …

In this paper a robust PID controller for quadrotor unmanned aerial vehicles is proposed that
uses the parameter space approach. Stability and robustness analyses are carried out in the …

This paper introduces and compares two robust control techniques estimating disturbances
for small-scale unmanned helicopters: adaptive disturbance rejection control (ADRC) and …

This paper presents a high-gain extended observer-based adaptive sliding mode scheme
for a quadrotor rotorcraft influenced by turbulent wind gusts while performing a defined …
