摘要
针对T-S模糊模型辨识步骤中,结构辨识与参数辨识混在一起、计算量大的缺点,提出了应用确定模糊规则结论参数的启发式辨识方法。对启发式辨识方法的基本原理做了阐述,并将基于该方法的T-S模糊模型应用于火电厂主汽温系统。以某600MW直流锅炉高温过热器为研究对象,对其不同工况下的单位阶跃响应模型进行了辨识。仿真结果表明,该T-S模糊系统能有效地逼近主汽温系统阶跃响应模型,验证了所提出的辨识算法的有效性和可行性。
To overcome the large computation amount in the identification of T-S fuzzy mode, a heuristic method is proposed. The basic principles of this method are formulated. A T-S fuzzy model based on this method is applied to the superheated system in heat-engine plant. A 600 MW direct current boiler's superheater is used as the research object. Step responses in different operation conditions are identified. The simulation result shows that the proposed method is feasible.
