小波分析理论是近年发展起来的一个新的数学分支.为了研究Wavelet分析理论在控制问题中系统辨识领域的应用,提出了Wavelet模型并分析了其结构和特征.同时,引入Laguerre模型作为与Wavelet模型进行对比研究的对象,剖析了两者的相同之处及差异.通过将Laguerre模型与Wavelet模型同时应用于构造具有延时因子的线性系统的模型中,经分析比较,发现Wavelet模型优越于Laguere模型.
Wavelet analysis theory is a new branch of mathematics developed in recent years. In order to study the application of Wavelet analysis theory in the field of system identification in control problems, a Wavelet model is proposed and its structure and characteristics are analyzed. At the same time, Laguerre model is introduced as the object of comparative study with Wavelet model, and the similarities and differences between the two models are analyzed. By applying Laguerre model and Wavelet model simultaneously to the model of linear system with delay factor, it is found that Wavelet model is superior to Laguere model.
