| 摘 要： | 提出一种基于新的模糊模型和加权递推最小二乘算法 (WRLSA)的非线性系统模糊辨识方法.新型的具有插值能力的模糊系统可以通过学习从输入输出采样数据中提取MISO系统模糊规则,它继承了Sugeno模型及其变化形式的许多优点.采用相应的模糊隶属函数,使得被辨识的模型可用若干局部线性模型来表示,然后利用WRLSA拟合这些线性模型.给出了详细的模糊辨识算法,为了验证该辨识方法的有效性,还给出了对熟知的Box-Jenkins数据的辨识结果. |

| Abstract: | A fuzzy identification method for nonlinear systems is suggested based on a new fuzzy model and weighted recursive least square algorithm (WRLSA). The new fuzzy system with interpolating capability extracts fuzzy rules of MISO system from input-output sample data through learning, and inherits many merits from Sugeno-type models and their variations. Through using suitable fuzzy membership function, the identified fuzzy model can be described by several local linear models. And finally, WRLSA is used to fit these linear models. The new fuzzy identification algorithm is proposed. To demonstrate availability of the identification method, the well-known Box-Jenkins data set is also identified. |
