Model Predictive Control of Once Through Steam Generator Steam Quality

IFAC-PapersOnLine, 2015
Abstract Steam quality is a critical process variable in the once through steam generator (OTSG) operation. However, the lack of online measurement and closed loop control of steam quality limits the efficient operation of OTSGs. To resolve this problem, this paper presents a model predictive control (MPC) solution based on soft sensor measurement ...
