{"title":"Frequency Locked Phase Estimation","authors":"A. Krieger, J. Salmon","doi":"10.1109/CCECE.2007.146","DOIUrl":"https://doi.org/10.1109/CCECE.2007.146","url":null,"abstract":"A novel method of synchronization is proposed for the estimation of the phase of the fundamental component of harmonically distorted power line voltage. Common phase synchronization techniques involve a multiplication of the line voltage signal with an estimate of the fundamental line voltage component, to measure the discrepancy between the line phase and the estimated phase, and this results in undesired frequency components in the phase error signal. These new frequency components cause ripple in the output phase estimation, which can typically be reduced by low-pass filtering following the phase detection, at the expense of slowing down the overall dynamic response of the synchronization process. To address the harmonic distortion in the line voltage signal, the proposed method measures the phase error by directly subtracting the incoming signal from a one-cycle delayed copy of this same signal. This error signal is then used to adapt the sampling rate to maintain a fixed ratio of sampling to line signal frequencies. For a harmonically distorted signal, this produces a zero steady state phase error signal, and a ripple-free sampling frequency. This sampling clock signal serves to operate a fixed discrete frequency quadrature signal generator, used to perform a sliding correlation of the input signal with the quadrature signals, to extract an estimate of the line voltage fundamental component. The principal feedback loop in the proposed method aims only at frequency tracking, resulting in faster overall response. Simulation results are presented to validate this proposed method.","PeriodicalId":183910,"journal":{"name":"2007 Canadian Conference on Electrical and Computer Engineering","volume":"467 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115322441","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}

Gu","doi":"10.1109/CCECE.2007.309","DOIUrl":"https://doi.org/10.1109/CCECE.2007.309","url":null,"abstract":"This paper presents the analysis, design, and the implementation of a system for detecting an electrical outlet that will allow a mobile robot to independently recharge its own energy supply. The system is implemented with a robotic arm, a zoom camera, a standard web camera and a laser distance sensor. Utilizing the eye-in-hand configuration the camera is mounted on end-effectors of the robotic arm. The image-based visual servo will control robot joint angles directly using measured image features. The image analysis is performed using Pattern algorithm. The robotic arm will start scanning the area trying to find an outlet. The system uses a template to be compared with the image coming from the camera; the zoom of the camera moves according to the distance of the object, which allows the system to compare with only one size template. Once the outlet has been identified, the coordinates x, y and z are sent to the robot. The robot will automatically move as close as necessary to the outlet then the robotic arm maneuvers using visual servoing until the plug face is perfectly aligned to the outlet; finally the plug/unplug system will be activated. Some simulation and experimental results will be given in the paper.","PeriodicalId":183910,"journal":{"name":"2007 Canadian Conference on Electrical and Computer Engineering","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117158445","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}
