约束预测控制在低氮燃烧机组过热蒸汽温度控制系统中的应用
Application of Constrained Predictive Control in Steam Temperature Control System of Low NOx Combustion Power Unit
摘要
Abstract
In view of the problems of combustion delay and steam temperature heavy fluctuation in the generation process of a low NOx combustion power plant,a predictive control algorithm with constrained optimization is proposed and applied to the superheated steam temperature control system of the power plant to construct a cascade compensation predictive control system,which is verified through simulation.The simulation results show that with the constraints of the superheated steam temperature cascade predictive control system,the controlled variable can be restrained effectively within the constraint range,and the system has the anti-jamming and robustness characteristics better than those of the conventional control system.Therefore,the superheated steam temperature control quality has been greatly improved.关键词
