Quadrotor Transporting Cable Suspended Load using ADRC
2019 Chinese Control Conference (CCC), 2019In 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, 2014Active 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), 2019Traditional 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, 2015Active 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, 2019Abstract 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), 2018This 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
2009The 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
2020In 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 ...

Interactive ADRC design for flight attitude control
2017 6th Data Driven Control and Learning Systems (DDCLS), 2017Flight vehicle attitude control is of great importance. In this paper, a flight controller based on active disturbance rejection control (ADRC) is proposed. Then stability margin tester is utilized to tune the parameters of the controller to meet the specified stability margins, which will serve as a practical tuning method in practice.
