The stator is connected to the isolated load. Only one bidirectional converter with a battery is employed on the rotor side. The direct voltage control (DVC) is applied to control the DFIG system. To regulate the voltage and frequency load, the error of the measured rotor current and reference value feed the hysteresis regulator, the output of which are the control pulses. The reference rotor currents are obtained by the DVC technique. Simulation results for a 3.7 kW prototype DFIG are presented in this paper.","PeriodicalId":128530,"journal":{"name":"2015 16th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128700517","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}

We rely on imperceptibility and robustness as a measure of performance of a watermarking algorithm. Seven wavelet families are used to generate the carrier signal. We insert the watermark message in approximation as well as in different subbands, at a different level of transformation in each wavelet, one at a time. To test the robustness, the watermarked image was subject to several attacks: JPEG, gamma correction, median filter and Gaussian noise.","PeriodicalId":128530,"journal":{"name":"2015 16th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121388551","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}

In addition, a control via Exact State Input Linearization requires rigorous conditions as well as the determination of a suitable diffeomorphism. In fact, the main objective of this paper is the analysis and resolution of the difficulties of the Exact State Input Linearization formalism by developing an analytical approach which my lead to the pratical implementation of this formalism. Thus, the stability region is studied so as to determine the stability of such a system. These two studies will be applied to a preliminary example.","PeriodicalId":128530,"journal":{"name":"2015 16th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114695532","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}

Having a simple construction with neither winding nor magnets in the rotor, the SRM has a doubly salient stator synchronous and singly excited throw it the torque is simply developed due to reluctance variation. Nevertheless, the switched reluctance machine still has incapacities such as a ripple torque and acoustic noise. Thus, many issues for hybrid electric vehicle application requirements have been developed to reduce the torque ripple and ensure more stability and less noise. Based on static characteristics as torque and flux linkage, the nonlinear model of switched reluctance motor is represented for a 12/8 SRM model aimed to a starter alternator application in this paper using MATLAB/Simulink to recognize an optimal choice of turn-off angle and suitable controller and converter for the torque and speed optimization.

They gave us the chance of collecting data from noisy environment. So it becomes possible to obtain precise and continuous monitoring of different phenomenons. However wireless Sensor Network (WSN) is affected by many anomalies that occur due to software or hardware problems. So various protocols are developed in order to detect and localize faults then distinguish the faulty node from the right one. In this paper we are concentrated on a specific type of faults in WSN which is the outlier. We are focus on the classification of data (outlier and normal) using three different methods of machine learning then we compare between them.
