The gearbox is driven by an induction motor and the output shaft of the gearbox is connected to a DC generator and a DC tacho-generator. The ripple current and voltage signals supplied by these generators are analyzed for a defect-free gearbox and a defective gearbox with two teeth missing in a particular gear. Multiresolution Fourier transform is applied to these signals in order to improve the signal to noise ratio as well to highlight a specific bandwidth of the signal containing all the gear mesh frequencies. It is found that application of MFT improves the dynamic range of the signal, and hence highlights the frequencies with negligible amplitude. The technique is observed to be effective in distinguishing the defective and the defect-free cases of the gearbox.","PeriodicalId":103105,"journal":{"name":"2006 IEEE International Conference on Industrial Technology","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121192316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper puts forward a novel algorithm to fuse mid-wave and long-wave infrared images and detect targets. Firstly, the source images are decomposed by wavelet transformation. In usual, targets in infrared images are man-made, and their fractal dimension is different comparing with natural background. In wavelet transformation domain high-frequency part, we calculate local fractal dimension and set up fusion rule to merge corresponding sub-images of two matching source images. In low-frequency, we extract local maximum gray level to fuse them. Then reconstruct image by wavelet inverse transformation and obtain fused result image. In fusion results, the contrast between targets and background has obvious changes. And targets can be detected using contrast thresholding. The experimental results show that the method using fractal dimension to fuse dualband infrared images, and then detect targets is superior to use mid-wave or long -wave infrared images detect targets alone.","PeriodicalId":103105,"journal":{"name":"2006 IEEE International Conference on Industrial Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121219189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A critical issue in control of this converter is current commutation as no freewheel path is available for the load current. In this paper, FPGA implementation of a semi-soft four-step commutation technique based on output current direction in matrix converter is presented. The same program can be used for implementing a three-step commutation process. A universal and synchronous commutation scheme for all the IGBTs is devised so that commutation can smoothly take place as and when required within the minimum possible time depending on the switching times of the IGBT used. The program logic is tested with the program simulator under various critical conditions.","PeriodicalId":103105,"journal":{"name":"2006 IEEE International Conference on Industrial Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116535553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adjustable speed drives are invariably supplied from a voltage source inverter. Proper modelling of voltage source inverters is important in devising appropriate control algorithm. This paper develops complete model of a five-phase voltage source inverter based on space vector approach. Both ten-step operation and pulse width modulation modes are elaborated. The Fourier analysis of output phase-to-neutral voltage is performed for ten-step mode of operation. The output phase-to-neutral voltage is shown to be essentially identical to those obtainable with a three-phase voltage source inverter. The inverter developed model is verified using simulation.","PeriodicalId":103105,"journal":{"name":"2006 IEEE International Conference on Industrial Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
