摘要
针对电厂主蒸汽压力这样一个大迟延、大时间常数的调节对象 ,讨论了以炉膛辐射信号作为中间被调量构成串级调节系统以改善其调节品质的可行性。考虑到炉内剧烈的湍流燃烧造成得到的炉膛辐射信号包含随机分量 ,不适宜直接用于组成串级系统 ,为此设计了一个模糊判断器加入到串级系统中组成一个新型的串级模糊调节系统。经仿真试验研究表明 。
In furnace control, main steam pressure is a big\|lagged and big\|inertial object. In this paper, the cascade control strategy is presented to improve its regulated quality, which uses the radiation signal as intermediate regulated variable. Consider that the radiation signal of the furnace contains random variable, it isn`t able to use as intermediate regulated variable directly. Instead, a fuzzy judger is designed and added to the cascade control system. Finally simulation result shows that the cascade fuzzy control system works well.
