针对供热网中大时滞现象 ,提出了一种新的模糊控制器结构 .这种模糊控制器通过在线辨识广义时滞 ,将时滞辨识的结果模糊化 ,决策出模糊规则组 ,填充主模糊规则表 ,达到自适应的目的 .作为应用 ,给出基于集中供热网温度控制的模糊控制器的设计 ,以解决控制对象中由大时滞和时变引起的不易控制和参数调整困难的问题 Aiming at the large time delay phenomenon in heating network, a new fuzzy controller structure is proposed, which fuzzy inference identifies the generalized time delay on-line, fuzzifies the result of time-delay identification, decides the fuzzy rule set, Fuzzy rules table, to achieve the purpose of adaptation.As an application, the design of fuzzy controller based on the temperature control of central heating network is given to solve the difficult control and parameter adjustment caused by large time-delay and time-varying in the control object problem
