摘要
本文对小波分析的概念、特点和在控制系统中的应用进行了综述。在对小波变换与傅立叶变换进行深入比较的基础上,对小波分析在故障诊断、信号检测和非线性系统建模等控制问题中的应用研究进行了简单的阐述,指出了小波分析在非线性系统建模等控制领域应用中的一些不足,并指出了在控制系统应用中小波分析进一步研究的方向。
The notion and major characteristics of wavelet are introduced in the paper. Wavelet transform is compared with fourier transform in this paper. Then the applications of wavelet analysis in control system fault diagnosis, signal detection and modeling of nonlinear system are simply stated. The shortcomings of the application of wavelet analysis are pointed out and some research areas about wavelet analysis are introduced in the application of control system.
