Active Disturbance Rejection Control for Loading System
2020 Chinese Automation Congress (CAC), 2020In this paper, the active disturbance rejection control (ADRC) strategy is proposed for the loading system. The behavior of actual loading system is influenced by a variety of factors including the internal parameters uncertainty and external disturbances, which will be observed by the designed extended state observer (ESO) and compensated by the ...

Active Disturbance Rejection Control of Underwater Manipulator
2021In this study, a method of active disturbance rejection controller (ADRC) is presented for 2-DOF underwater manipulator. The ADRC basically does not rely on the accurate mathematical model of the object and can decouple the model. This method can eliminate the influence of model errors, time-varying parameters and external interference on the control ...

A survey on active disturbance rejection control
2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s), 2013The conventional PID controllers have been in existence in the process industry from its very birth for almost a century. The empirical approach of the PID presents a limitation in tuning for practising engineers, since it requires ample experience and a sound knowledge of the plant.

Active disturbance rejection control for electrical cylinder
2017 36th Chinese Control Conference (CCC), 2017The position tracking control problem of electrical cylinder in the presence of nonlinear friction load, inertia load and nonlinear disturbance due to its transmission process is addressed in this paper. To compensate all of these disturbances in the case of servo motion, active disturbance rejection control is used to make a continuous and precise ...

Active disturbance rejection controller for chemical reactor
AIP Conference Proceedings, 2015In the petrochemical industry, the synthesis of 2 ethyl-hexanol-oxo-alcohols (plasticizers alcohol) is of high importance, being achieved through hydrogenation of 2 ethyl-hexenal inside catalytic trickle bed three-phase reactors. For this type of processes the use of advanced control strategies is suitable due to their nonlinear behavior and extreme ...

Active disturbance rejection control for structural vibration
2014 14th International Conference on Control, Automation and Systems (ICCAS 2014), 2014Construction vibration is a fast responding, multivariable coupled dynamic system. In this paper, an active disturbance rejection control (ADRC) solution is proposed and tested on a certain three-storey building model. The proposed system with a decentralized structure is free from complex decoupling which is hard to practice in actual application ...

Modified active disturbance rejection control for fluidized bed combustor
ISA Transactions, 2020As a widely-used technology, fluidized bed combustor (FBC) boiler is facing many control challenges such as coupling, high-order dynamics and nonlinearity. With more and more sustainable energy integrating into the bulk power system, the FBC boiler is obliged to speed up the respond to the automatic generation control command and this results in great ...

Active disturbance rejection controller design for PMSM
2016 Chinese Control and Decision Conference (CCDC), 2016In this paper, according to the characteristic of permanent magnet synchronous machine drive systems, a 2nd-order speed output equation has been derived while the PI regulator for current-loop can be treated as a part of its mathematical model. Thus, the 2nd-order active disturbance rejection controller has been designed with discrete algorithms ...

Active Disturbance Rejection in Repetitive Control Systems
2021As a high-precision control method for periodic signals, repetitive control has been widely investigated from both theoretical and practical sides. Since a repetitive control system contains two completely different actions: continuous control within each repetition period and discrete learning between periods, exploring the best combination of these ...
