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.

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.

Linear Active Disturbance Rejection Control for Fast Nuclear Reactor
Volume 1: Operations and Maintenance, Engineering, Modifications, Life Extension, Life Cycle and Balance of Plant; I&C, Digital Controls, and Influence of Human Factors, 2017Since dynamics of a fast nuclear power reactor is quite nonlinear, uncertain and time-varying. Moreover, the reactor period depends on the neutron lifetime and it has a crucial importance in reactor power so it is necessary to have a control system for the reactor power.

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

Attitude control for spacecraft based on linear active disturbance rejection control technique
2015 IEEE International Conference on Information and Automation, 2015This paper studies the problem of attitude control for spacecraft with parameter uncertainties and unknown external disturbance. A linear active disturbance rejection controller (LADRC) with three channels for attitude control for spacecraft is designed to actively compensate for the disturbance and improve the system robustness.

Study of pneumatic servo system based on linear active disturbance rejection controller
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013To improve the robustness and the anti-disturbance of control system, regulate its stiffness, a scheme concluding linear active disturbance rejection controllers for pneumatic servo system is proposed. Two linear active disturbance rejection controllers are designed respectively to track the motion and pressure reference.

Linear Observer‐Based Active Disturbance Rejection Control of the Omnidirectional Mobile Robot
Asian Journal of Control, 2012AbstractThis article describes the design of a linear observer‐linear controller‐based robust output feedback scheme for output reference trajectory tracking tasks in an omnidirectional mobile robot. The unknown, possibly state‐dependent, additive nonlinearities influencing the input‐output tracking error dynamics are modeled as an absolutely bounded ...
