摘要: 讨论用模糊方法实现非线性系统在线辨识问题.首先给出了简化的模糊规则表达 方法及其相应的自适应模糊推理,在此基础上给出了模糊模型参数在线辨识算法.最后对 非线性模型进行在线辨识,验证了本文提出的模糊模型及其在线辨识算法.Abstract: Nonlinear system modeling using fuzzy system is discussed in this paper. A simple fuzzy rule representation method and the corresponding adaptive fuzzy inference are proposed. Based on this modified fuzzy system, the paper presents an on-line identification algorithm with which the on-line parameter estimation of nonlinear system is realized. A nonlinear model, as an example, is identified to verify the fuzzy system and identification algorithms.
