Active disturbance rejection control for boiler superheated steam temperature

In this paper, an active disturbance rejection control (ADRC) with tracking differentiator (TD) solution is proposed and tested on a certain four operating condition model. The proposed system with a cascaded control scheme is constructed based on a linear Active disturbance rejection controller (LADRC) with parameters optimized under a modified fruit fly algorithm. The tracking performance could be improved by the tracking differentiator with flexible damping. The simulation results indicate that the proposed strategy could effectively balance rapid and stable responses.
