Application Research of Several Improved Active Disturbance Rejection Control Methods for Superheated Steam Temperature System

IET Smart Energy Systems, Volume 2, Issue 1, Page 49-61, March 2026.
A series of improved active disturbance rejection controller (ADRC) methods are proposed, and their parameter tuning processes are presented. They are comprehensively compared with regular proportional integral (PI) control and ADRC, and detailed superheated steam temperature (SST) simulations are carried out to verify their notably superior control ...
