This paper presents a kind of soft-sensing method of oxygen content in flue gas based on new generalized predictive control (GPC) algorithm.Contrastive measurement of oxygen content in flue gas between soft sensor based on traditional GPC algorithm

zirconia sensor and the method in this paper is done

whose results show that the soft sensor structured by new GPC algorithm can reflect the actual conditions of any period time in boiler combustion process

improves the measurement precision and optimizes the capability of boiler combustion control coefficients.Soft-sensing technique of oxygen content in flue gas based on new GPC algorithm provides a new method for industrial boiler oxygen measurement

paves a new way for key parameters measurement

such as accurate

real-time

on-line soft sensing of gas temperature

and has significant meaning for the realization of combustion system’s closed-loop control and optimization running.
