Parametric and nonparametric identification of shell and tube heat exchanger mathematical model [PDF]

open access: yes, 2012
Parametric and nonparametric models of a shell and tube heat exchanger are studied. Such models are very important because they provide information about controlling a system operation. Without the model, the control task would be difficult for tuning
