摘　　要：针对化工生产过程中强非线性对象的动态建模问题，本文提出了具有代表性的连续搅拌反应釜的非机理模糊建模方法。从系统的输入输出数据出发，根据辨识精度将系统空间划分为个子空间，然后由隶属函数将子空间模型联接成全局模型来表征系统的整体非线性特性。仿真结果表明，该模型输出能够很好地跟踪系统的参考输出，效果明显。Aims with the consideration of the dynamic modeling of the strong nonlinear object in the production processes of chemical industry, this paper presents the non-mechanism fuzzy modeling method of the typical CSTR system. As for the input-output data set, the input and output spaces are divided into M fuzzy snbspaces according to the identification precision, and then the local models are integrated into the global model to represent the whole nonlinear characteristics of the system by the membership function. The simulation result of the CSTR demonstrates that the model output of the method can accurately and effectively track the system＇s reference output..
