This paper focuses on the recent progress in the adoption of active disturbance rejection control (ADRC) in thermal processes as a viable alternative to proportionalintegralderivative (PID), especially in coalfired power plants. The profound interpretation of this paradigm shift, with backward compatibility, is discussed in detail. A few fundamental issues associated with ADRC's ...
