ADRC applied in chaotic arrhythmic heartbeats control

2015 15th International Conference on Control, Automation and Systems (ICCAS), 2015
Control arrhythmic heartbeats has always been an important issue in cardiology. In this work, the capability of active disturbance rejection control (ADRC) to suppress the chaotic arrhythmic heartbeats is studied. The modified Van der Pol model is employed as mathematical model to describe the normal and pathological heart rhythms.

Quadrotor Transporting Cable Suspended Load using ADRC

2019 Chinese Control Conference (CCC), 2019
In this paper, the stability and trajectory tracking of a quadrotor suspended load system are researched. There is a great coupling effect between the quadrotor and the suspended load, which has a great influence on the stability and trajectory tracking performance of the quadrotor.

On the stability of Han's ADRC

2014 American Control Conference, 2014
Active disturbance rejection control (ADRC) is a heuristic but highly effective approach to controller-observer design. The advantages of the approach have been demonstrated in many applications but there is little available on its stability analysis. This paper shows that the nonlinear function used in ADRC results in stable behavior. Two examples are

IEEE Micromouse control based on ADRC algorithm

2019 IEEE 4th Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2019
Traditional direct-current micromouse generally use PID control algorithm or fuzzy PID control algorithm to control, but PID series control algorithm has the disadvantages of slow response speed, easy overshoot and sensitivity to environmental changes. In the IEEE micromouse competition, these shortcomings of the control algorithm will cause the direct-

Decentralized ADRC for LFC in Deregulated Environments

International Journal of Engineering Practical Research, 2015
Active disturbance rejection control (ADRC) method is investigated in this paper to design decentralized load frequency controllers (LFC) for deregulated multi‐area power systems. ADRC can treat the connections among control areas and the effects of possible contracts as new disturbance signals, and uses an extended state observer (ESO) to estimate and

On External Disturbance Rejection of Linear ADRC

Volume 9: 15th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications, 2019
Abstract Active disturbance rejection control (ADRC) is a quickly developing practical control technology while its ability to reject external disturbance is necessary to investigate deeply. Focusing on the simple case that the plant is an exactly known second order plant, this paper investigates the external disturbance rejection of ...

PMSM Vector Control Based on Improved ADRC

2018 IEEE International Conference of Intelligent Robotic and Control Engineering (IRCE), 2018
This paper research a vector control strategy of PMSM based on ADRC technology. That is, using the vector control method, an ADRC is designed for the speed control loop of the PMSM to replace the PI controller. At the same time, in order to facilitate the parameter adjustment of the ADRC, some improvements are made to the typical structure of the ADRC,

ADRC for Uncertain Systems with Time-Delay

2009
The majority of control systems are operated by proportional-integral- derivative (PID) controllers, which dates back to 1922 ([135], [110], [220]) well before classical and modern control theory were born. Today, much work has been done related to systems with time-delays, see for example, ([188], [189], [154], [126]) and references therein. It should

ADRC-Based Wind Turbine Pitch Control Strategy

2020
In order to make the output power of the wind turbine more stable, a pitch control strategy based on auto disturbance rejection controller is proposed. When the wind speed received by the wind turbine is higher than the rated wind speed of the unit, By adjusting the pitch angle, the aerodynamic torque of the fan is changed, thereby stabilizing the ...
