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.

Dynamic Linearization Based Adaptive Nonlinear Active Disturbance Rejection Control
2019 IEEE 8th Data Driven Control and Learning Systems Conference (DDCLS), 2019This work deals with the control issue in disturbed discrete-time nonlinear nonaffine system. A novel adaptive nonlinear active disturbance rejection control based on dynamic linearization technique is designed. Through dynamic linearization technique, the nonlinear nonaffine system is translated into a linear parametric data model with a nonlinear ...

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: Analysis and Tuning via IMC
IEEE Transactions on Industrial Electronics, 2015Linear active disturbance-rejection control (LADRC) is investigated in this paper. First, it is shown that LADRC structure can be changed to a two-degree-of-freedom (TDF) internal model control (IMC) structure, where the nominal model for the IMC design is simply a multiple integral plant, so analysis of LADRC can be done via the IMC framework. Then it
