Abstract

A method is developed to combine multiresolution analysis with fuzzy system to build dynamic system model. The proposed method consists of two parts, the construction and application of model. To construct the model, the signals are decomposed respectively to form data pairs on different scale and, the data pairs are used to construct the model on different scale whose output will be reconstructed to approximate the original signal. When this method is put into use, a certain length of past signal and current signal are used to predict the model output and, at next time instance, the past signal is push forward. This is a repeated procedure. The simulation shows the method is effective.

基于多分辨率分析的模糊建模研究
提出了一种将多分辨率分析与模糊系统相结合建立动态系统模型的方法。该方法由模型的构建和应用两部分组成。在构建模型时,分别对信号进行分解,形成不同尺度的数据对,利用这些数据对构建不同尺度的模型,对模型的输出进行重构,使其近似于原始信号。该方法使用时,用一定长度的过去信号和当前信号来预测模型输出,在下一个时间实例中,将过去信号向前推。这是一个重复的过程。仿真结果表明该方法是有效的。
