Application of active disturbance rejection controller to water supply system

The work analyses the use of an active disturbance rejection control (ADRC) structure in a constant water pressure management system. The adaptability and robustness of the proposed control scheme significantly enhances the performance of a conventional PID-based output feedback control loop. The paper investigates the ADRC approach with a set of experiments conducted on a laboratory-scale model of a water supply system. The proposed approach is also compared with the results obtained for the sole conventional industrial PID controller.
