【Abstract】 The gas power plant employs DCS to control its boilers and the conventional PID control has poor control effect in practice. In this paper,the generalized predictive control( GPC) and adaptive fuzzy control were used to realize advanced control of the relevant loops and a set of advanced control system for gas power plant boiler was constructed and successfully applied to the combustion system and steam water system. Field application shows that,the advanced control system has good effect and the control quality of related circuits has been improved obviously.更多还原
