simple nonlinear drum boiler model
Nonlinear Control Oriented Boiler Modeling-A Benchmark …
simple linear models as well as high order and nonlinear ones were considered. In a later study, Astrom and Bell developed a model [3] which relied more on first principles, and therefore, was likely to better represent the internal drum dynamics. of of plant 4

[PDF] Drum-boiler dynamics | Semantic Scholar
Drum-boiler dynamics. Autom. This paper describes a nonlinear dynamic model for natural circulation drum-boilers. The nonlinear model which is intended for model based control focuses on the complicated dynamics ofthe drum, downcomer, and riser components. A strong effort has been made to strike a balance between fidelity and simplicity.
