Ph Neutralization Process Control Using Linear Active Disturbance Rejection Control
2018 15th International Computer Conference on Wavelet Active Media Technology and Information Processing (ICCWAMTIP), 2018PH is the measure of acidity or alkalinity of a solution containing water, which has a wide usage in industry. The extreme nonlinearity and exposure to the effects of multivariable pH processes makes it an appropriate test bed for evaluation of controllers.

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 With Partially Canceling Estimated Total Disturbance
2019 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2019Active disturbance rejection control (ADRC) is a quickly developing practical control technology while its tuning is an important research topic. The current mainstream tuning method entirely cancels the estimated total disturbance and results an integrator in linear ADRC's feedback compensator, thus limits the ability to meet design specification of ...

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 ...

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 for a raceway photobioreactor
Control Engineering Practice, 2019Abstract In this paper, the problem of pH regulation in photobioreactors has been addressed by using a robust Proportional–Integral controller in combination with a linear active disturbance rejection approach. This formulation is based on the Generalized Proportional–Integral (GPI) observers design to estimate online external disturbances and non ...

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

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.
