In this paper, we report a comparative study to evaluate the performance of the six algorithms for QT interval prolongation measurement with computer-simulated ECGs based on a whole-heart model. Artificial zero-mean Gaussian noise with variable signal-to-noise ratios (SNR) was added to the simulated ECGs for quantitative evaluation of these algorithms with variations thresholds. The study showed that, the measurement accuracies of these six methods augment with the increase of the SNR of simulation data, while the variations of threshold of these methods have little influence on the measurement accuracy of QT interval variation. Through evaluating the QT interval prolongation values measured from the same simulated ECGs contaminated with noises, the best performance was obtained from the continuous wavelet transform based method with the mean error less than 1 ms even when the SNR is as low as 0 dB. Our study suggests that the continuous wavelet transform based method may outperform the traditional methods in estimating QT interval prolongation for ECGs with strong noise as evaluated with artificial ECGs.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126373841","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}

VSC offers insensitive to parameter variations and external load disturbances. However, VSC exponential stability is guaranteed when the upper bound of the system uncertainties is known. Therefore, the chattering may produce. In order to overcome the chattering, the grey prediction compensation is used for pulse-width modulation (PWM) inverters and afterwards the low total harmonic distortion (THD) sinusoidal voltage in the inverter output can be obtained. The results verify that VSC with grey prediction significantly eliminates the chattering and its performance is compared with the classic VSC.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131353003","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}

Recently, sensorless induction motor drives have been much studied due to several advantages, and various sensorless algorithms for an induction motor drive have been proposed. Most sensorless control algorithms are based on the flux and speed estimations which are obtained from the voltage equations. Therefore, the sensorless control performance is largely influenced by the parameter errors of a motor. This paper investigates an improved sliding mode observer with the parameter error compensation for the speed sensorless control of an induction motor. The proposed parameter estimation is obtained from the error between the measured and decoupled currents. The performance of the proposed algorithm is verified through the simulation and experimentation.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132344928","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 conventional CRLH TL unit cell is used as the basic elements for the design of time-delay lines and a rotated version of the unit cell is used to achieve ultrawide bandwidth operation. Time-delay lines for large time delays are designed by cascading the proposed unit cells, optimized using computer simulation and then fabricated on PCBs. A compact UWB time-delay line is designed by bending the time-delay line in a meander. For comparison, the time-delay line using the right-handed transmission line (RH TL) is also fabricated. Simulation and measurement results show that our proposed time-delay lines have ultrawide bandwidth operation and much longer time delays than that of the time-delay line based on RH TL.
