Abstract

Aiming at the large time-delay and fast time-varying characteristics of steam temperature system of Circulating Fluidized Bed Boiler (CFBB), steam temperature properties effected by spray-water and feed-water are studied in different steam load. Multi-model forward-feedback adaptive dynamic matrix predictive control strategy is proposed. The new method has ability of overcoming some shortcomings while single model used, and eliminate the coupling property from feed-water varying. Simulation results show that the proposed predictive control method has better control quality, stronger robustness and good adaptive capacity.
