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, 2017 Since 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.

A Relay Feedback Method for the Tuning of Linear Active Disturbance Rejection Controllers [PDF]
IEEE Access, 2020 Active disturbance rejection control (ADRC) is a new control method that estimates the total disturbance by an extended state observer and compensates it by a state feedback law, and good disturbance rejection performance is expected compared to traditional PID control method.

A Linear Active Disturbance Rejection Control for a Ball and Rigid Triangle System [PDF]
Mathematical Problems in Engineering, 2016 This paper proposes an application of linear flatness control along with active disturbance rejection control (ADRC) for the local stabilization and trajectory tracking problems in the underactuated ball and rigid triangle system. To this end, an observer-based linear controller of the ADRC type is designed based on the flat tangent linearization of ...
