This example of AC-DC-AC converter illustrates use of Universal Bridge, Multimeter, and Powergui blocks, as well as discrete control blocks of the Extras library.(A 60 Hz, voltage source feeds a 50 Hz, 50 kW load through an AC-DC-AC converter. The 600V, 60 Hz voltage obtained at secondary of the Wye/Delta transformer is first rectified by a six pulse diode bridge. The filtered DC voltage is applied to an IGBT two-level inverter generating 50 Hz. The IGBT inverter uses Pulse Width Modulation (PWM) at a 2 kHz carrier frequency. The circuit is discretized at a sample time of 2 us)

retinex阴影去除 non linear processing on the image by the commercial camera used
Sensors are not Dirac Delta Functions but narrow band
Approximate invariant angle is obtained by the entropy minimization mehtod. Exact angle can only be found by camera calibration method(retinex shadow removing，non linear processing on the image by the commercial camera used

子波分析是一种日益获得广泛应用的信号处理新技
术, 具有良好的时-频局部化特性, 尤其适用于时变及非平
稳信号。本文简述了子波函数与子波展开的基本概念, 利用
展缩子波和调和子波将信号及信号均方值进行时-频两维
分布。最后采用了三种子波分析方法对轴承故障进行诊断,
即使对现有各种方法尚难以诊断的滚动体故障, 也能获得
满意的结果, 说明子波分析的确为机械故障诊断提供了强
有力的分析手段。(Wavelet a nalysis, as a new technique of signal processing , possesses ex cellent characteristic
of time-frequency localization and is suitable for analyzing
the time-var ying or transient signals. In this paper , the basic concepts of wavelet function and
wavelet expansion are briefly introduced. The time frequency
distribution of signal and its energy are obtained by decomposition via dilating wavelet and harmanic wavelet. )
