Abstract. In this paper, based on the real, acceptable assumptions,
first nonlinear and then linearized mathematical model of the pulverising
plant, are developed, which include, for the first time, the dynamics of
the coal drying process having significant influence on the overall dynamic
behaviour of the considered plant. The obtained model can be used efficiently
for the analysis as well as for the synthesis of control for this complex
energy process.
MATEMATIČKI MODEL PULVERIZACIONOG POSTROJENJA
KAO AKUMULATORA MASE
SA DINAMIKOM VENTILATORSKOG MLINA I PROCESA
SUŠENJA UGLJA
U datom radu polazeći od realnih prihvatljivih pretpostavki, razvijeni
su prvo nelinearni a onda i linearni matematički modeli pulverizacionog
postrojenja, koji uključuju, po prvi put, dinamiku procesa sušenja uglja
koja ima značajan uticaj na ukupno dinamičko ponašanje celokupnog postrojenja.
Dobijeni model može se uspešno iskoristiti u analizi kao i u sintezi upravljanja
ovim složenim energijskim procesom.
