| 摘 要： | 热工过程对象通常具有复杂的动态特性和非线性、强耦合、不确定性等特征,从而使得常规建模方法难以取得满意的效果,因此提出一种改进型TS模糊模型在线建模方法。此建模方法基于以下思想,首先提出基于中心粒群算法的截集模糊C-均值聚类算法并对TS模糊模型进行模型结构离线辨识,确定模型的结构和前件部分参数的初始值;然后应用解耦扩展卡尔曼滤波算法进行后件参数在线辨识,同时对前件辨识结果进行精确修正。最后,对煤气炉、500MW机组及气化炉等热工过程进行仿真计算表明本方法具有精度高、计算量小等优点。

| Abstract: | Considering the complex dynamic behaviors,nonlinearities,strong coupling,and time-varying characteristics of the thermal process,a modified online modeling method based on TS fuzzy model was proposed and applied.The modeling method is on the base of the following ideas: firstly,the sectional set fuzzy c-means clustering based on center particle swarm optimization was proposed to identify the model structure off line and the initial values of the antecedent parameters.Secondly,the decoupled extended Kalman f... |
