说明： 虚拟仪器代表着目前测试仪器领域的发展方向，LabⅥEw语言是一种功能强大的仪器开发平台。对淹没在噪声中声发射信号的有效提取(去噪)是声发射信号处理技术的第一步，也是声发射信号处理的关键所在。本文介绍了基于小波变换的阈值去噪方法。在LabⅥEw平台上，通过仿真试验，对声发射信号的几种阈值法的去噪结果进行比较，选出一种适合声发射信号去噪的阈值准则。(Virtual instrument on behalf of the current developments in the field of testing equipment direction, Lab Ⅵ Ew language is a powerful development platform apparatus. Submerged in the noise of the acoustic emission signal in the effective extraction (denoising) is the acoustic emission signal processing technology, a first step, the acoustic emission signal processing is the key. In this paper, based on wavelet transform thresholding denoising method. Lab Ⅵ Ew in the platform through the simulation of acoustic emission signals of several denoising threshold method for comparison of results to elect a suitable acoustic emission signal de-noising threshold criteria.)

说明： Recent advances in the relevant technologies of
contemporary wireless sensor nodes has motivated a growth in
the deployment of wireless sensor networks (WSN) for
commercial, non-commercial and research applications. In the
aforementioned applications, it is often prudent to frustrate
unauthorised wireless communications with WSN nodes.

Diagnosis-and-Fault-Tolerant-Control
In this work we introduce a recent implicit fault tolerant control technique for the permanent magnet synchronous machine. After a state of the art in the FTC domain, we elaborate the complete model of the machine witch allow to study its behavior in different cases. The unknown torque load and parametric variations are compensated by the robust backstepping control low but in order to detect and compensate faults, we use this technique witch we study in detail. We also propose a new method for generating compensation terms in the control low.
