Inclusive modelling and parameter estimation of a steam

The boiler dynamics and the amount of generated power by the boiler should be specified to model the coordinated turbine–boiler control mode in steam units . In [15-18], the mathematical model of the drum-type boiler has been discussed. The proposed boiler model contains fuel dynamics, water-walls, and the generated steam pressure in the drum.
