一种参数自适应模糊 PI 控制器在超临界磨煤机出口温度控制系统的应用研究
Application Research on a Kind of Parameter Self-adaptive Fuzzy PI Controller in Exit Temperature Control System of Supercritical Coal Mill
摘要
Abstract
Aiming at demerit of difficulty in controlling exit temperature of coal mill,a kind of parameter self-adaptive fuzzy proportional-integral control strategy was proposed which was able to conduct online adjustment for proportional factor of the output part of PI controller by combining real-time trend with fuzzy control rule base in controlling process. When en-trance temperature was changing,the cold wind door baffle opening was dynamically controlled in order to realize system output equal to given temperature and improve dynamic characteristic of exit temperature control system of the coal mill. According to commissioning testing data of the supercritical unit and related changing curve,this optimization control strate-gy was proved to be of advantages such as strong anti-interference,adaptability for variable working conditions and follow-ing ability. In addition,this strategy was proved to be provided with stronger adaptability and robustness than conventional control strategy.关键词
