Linear Active Disturbance Rejection Control for Course Keeping in Harbor
Proceedings of the 3rd International Conference on Electronics, Communications and Control Engineering, 2020Due to the low speed and shallow water effect of the ship when sailing in harbor, the parameters of the ship model are changed, and the traditional PID autopilot cannot effectively control the ship's course. In this paper, the effects of changes in water depth and ship speed on the ship are transformed into changes in ship model parameters, and ship ...

A generalized active disturbance rejection control approach for linear systems
2015 IEEE 10th Conference on Industrial Electronics and Applications (ICIEA), 2015A generalized active disturbance rejection control (ADRC) approach is proposed for general linear systems. The method follows the idea of the conventional ADRC by using extended state observer (ESO) to estimate the generalized disturbance and using it in the feedback control to attenuate it quickly.

Linear Active Disturbance Rejection Control for Isolated Three-Port Converter
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018Because of the coupling and interaction of power delivery among the different ports in isolated three-port converter (TPC) and the small signal linear control model derived from specific steady state point, the parameters of control models will be varied with the change of operation state, this might result in degradation of control performance.

A new method to tune linear active disturbance rejection controller
2016 American Control Conference (ACC), 2016Linear active disturbance rejection control (ADRC) is known for its simplicity and its performance in disturbance attenuation. Currently, tuning of linear ADRC is via the bandwidth idea proposed in [1]. It is first shown that there are some limitations using only two bandwidths to tune the linear ADRC controllers.

Linear Active Disturbance Rejection Control Tuning Approach Guarantees Stability Margin
2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018This paper investigates the frequency properties of linear active disturbance rejection control. For stable or critical stable second-order LTI plants, it proposes a new parameter tuning approach. The approach is proved that can guarantee the closed-loop has a given gain crossover frequency and a phase margin no less than a given value between 32 ...

Analysis and Tuning of General Linear Active Disturbance Rejection Controllers
IEEE Transactions on Industrial Electronics, 2019General linear active disturbance rejection control (LADRC) is studied in the paper. First, it is shown that there are some limitations in the conventional LADRC, and then some properties of general LADRC are analyzed. It is proved that any strictly proper controller with integration can be implemented via a general LADRC, thus extends the application ...

Linear Active Disturbance Rejection Control for Piezo-Fexural Nanopositioning Stage
2017Piezoelectric actuators are commonly used in nanopositioning stages. Due to the hysteresis of piezoelectric actuator, accurate position control of a nanopositioning system is always a challenging task. In this paper, linear active disturbance rejection control (LADRC) is designed to address hysteresis.
