【摘要】 针对燃煤电厂湿法脱硫系统的浆液pH值控制过程中存在的高度非线性、时滞性及各种不确定性,提出了自优化模糊串级控制策略。经仿真验证及某电厂工程应用,自优化模糊串级控制提高了吸收塔浆液pH值控制系统的稳定性,增强了系统的鲁棒性和适应性。更多还原

【Abstract】 Based on the altitude non-linearity, time-delay and a large number of uncertainties existed in the slurry PH value control of the wet desulphurization system in the coal-fired power plants, the paper puts forward the self-optimizing fuzzy cascade control strategy. The self-optimizing fuzzy cascade control can improve the stability of the slurry PH value control system and enhances robustness and adaptability through simulation validation and engineering application in a certain power plant.更多还原
