Linear Active Disturbance Rejection Control Design for Single-Phase UPS Inverters
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021This paper presents a step-by-step analysis of the Linear Active Disturbance Rejection Control (LADRC) for single-phase Uninterruptible Power Supplies (UPS) application. In UPS application, the regulated output voltage with low Total Harmonic Distortion (THD) under different load conditions and disturbances is the desirable. To achieve this goal, LADRC

Quadrotor modeling and control based on Linear Active Disturbance Rejection Control
2016 35th Chinese Control Conference (CCC), 2016This paper investigates an integrated process for design of the control system of a small quadrotor. A twelve degree of freedom dynamic model of the oblique cross quadrotor is first established. Then, to cope with the quadrotor's nonlinear and under-actuated characteristics, Active Disturbance Rejection Control (ADRC) systems are designed. Moreover, to

Ship tracking control based on linear active disturbance rejection control
2012 Third International Conference on Intelligent Control and Information Processing, 2012Owing to ship's high inertia, strong time lag, non-linearity and under-actuated characteristics, as well as sustaining external disturbances frequently, designing a high performance ship tracking controller is still one of the most important research topics of ship motion control.

Linear Active Disturbance Rejection Control Based on UKF Identification
2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC), 2018To improve the estimation result of the linear extended state observer (LESO), we propose a linear active disturbance rejection control strategy based on the UKF identification. We use the UKF identification method to identify the unknown parameters of the system model and the controller gain $\mathrm {b}_{0}$ of the linear active disturbance rejection

Linear Active Disturbance Rejection Control From the Practical Aspects
IEEE/ASME Transactions on Mechatronics, 2018In this paper, important issues that could come up in practice of active disturbance rejection control (ADRC) due to a common assumption and some inevitable practical restrictions are investigated. The main idea behind ADRC is modeling effects of both internal uncertainties and external disturbances as an extra state called the total disturbance which ...

A generalized active disturbance rejection control approach for linear systems
2015 IEEE 10th Conference on Industrial Electronics and Applications (ICIEA), 2015A generalized active disturbance rejection control (ADRC) approach is proposed for general linear systems. The method follows the idea of the conventional ADRC by using extended state observer (ESO) to estimate the generalized disturbance and using it in the feedback control to attenuate it quickly.

Non-linear active disturbance rejection control for upper limb rehabilitation exoskeleton
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2020Trajectory tracking in upper limb rehabilitation exercises is utilized for repeatability of joint movement to improve the patient’s recovery in the early stages of rehabilitation. In this article, non-linear active disturbance rejection control as a combination of non-linear extended-state observer and non-linear state error feedback is used for the ...

Linear active disturbance rejection control of quadrotor's altitude and attitude
2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2017The problem of how to control a quadrotor is investigated. A nonlinear model of the quadrotor is derived with Newton-Euler formulation and then simplified. With the simplified model, Linear Active Disturbance Rejection Control (LADRC) is used to control the altitude and attitude of the quadrotor.

Stability of sampled-data linear active disturbance rejection control: A classical control approach
2017 13th IEEE International Conference on Control & Automation (ICCA), 2017Stability of continuous-time and sampled-data LADRC is investigated with classical control approach. For the second-order uncertain LTI plant, the LADRC is described as an interconnection structure. Then sufficient conditions to guarantee continuous-time and sampled-data LADRC stabilizing the plant are proved respectively, while in proving the main ...

A linear active disturbance rejection control approach for near space vehicle autopilot
2015 International Conference on Control, Automation and Information Sciences (ICCAIS), 2015The conventional PID controller parameters are difficult to be decided on the dynamics of the near space vehicle within a large flight envelope. In this study, a linear active disturbance rejection control approach is proposed. The model perturbation is estimated by the extended state observer, and then the error of closed-loop system is compensated by
