In the present work, we consider norm-bounded parametric uncertainties. We show that the existence of the SOF for the closed-loop uncertain linear systems is cast as the feasibility of a set of Bilinear Matrix Inequalities (BMIs). Using some technical lemmas, the BMIs are transformed into LMIs, which are numerically exploitable. Thus, we present new LMI stability conditions for the SOF design using two different approaches. We show that our new LMI conditions are less restrictive compared with those available in the literature. A numerical example is illustrated in the end to show the superiority of our design method.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123292760","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 propose two neural models. In the first one, the outputs of the problem are the patch size and the resonant frequency for even modes. In the reverse side of the problem, the resonant frequencies for both even and odd modes are obtained in terms of the effective semi-major axis, eccentricity of elliptical patch, the thickness and the effective relative permittivity of the dielectric substrate. To enhance the accuracy of the two models, measurements have been included in the training stage. The two proposed models are very adequate for a fast and accurate estimation of the characteristics of the elliptical microstrip antenna.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129928550","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}

Based on the fault information maked by the fault-estimation procedure, the FTC component is constructed to compensate the effects of faults. FTC is developed to guarantee the desired stability and robustness in the presence of faults. A sufficient condition for stability with $H_{infty}$ performances and D-stability constraints is formulated as a linear matrix inequalities (LMIs) problem.

The challenging idea investigated in this work is to insulate the encryption process from the synchronization operations relying on the same chaotic system but with two different roles. First, the chaotic system is a part of the encryption process and generate pseudo-random sequence of signals, which will be treated with Exclusive-OR operations to form the cipher, and then the dynamic system will acts as a transmitter. In fact, the designed transmission scheme is established using an improved optimal nonlinear observer having the advantage to reconstruct the transmitter. Finally, the decryption operation is carried out by replacing the chaotic system by its estimation one. Numerical simulation based on an image encryption/decryption is conducted as an illustration to demonstrate the outstanding performances of the designed transmission method.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115496376","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 main objective of the control of the wind system in partial load power production is to require the maximum efficiency power flow transfer to the grid. Vector control strategy is well used to achieve this purpose where the conventional control design employs PI regulators for the adjusting of the currents loops. However these regulators are sensitive to parameters variations that results the degradation in the performance of the controlling system. This paper deals with an alternative controller for the DFIG generator based on internal model control strategy which the controller selected is an approximate inverse of the model. The design control was done with 5MW NREL DFIG using SimWindFarm toolbox Matlab/Simulink and compared with the classical proportional integral control to discuss the performance in terms of tracking references and sensitivity to parameters variations.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115783503","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}

Conventional means of security analysis are based on the resolution of load-flow equations for each contingency to compute a performance index (PI). This technique seems to be unsatisfying due to the time-consuming and intensive computational efforts. In this paper, we present an approach based on the combination of Fuzzy C-Means clustering (FCM) algorithm and artificial neural network (ANN) to classifying the power system status as critical, secure and insecure for a certain operating condition and a specified contingency. The training set of the FCM-ANN method is created through offline simulations. Then, Direct- Method is used in the feature selection process to reduce the dimensionality of the inputs. The security classification is performed with the help of the PI computed using Newton-Raphson load flow method. The proposed method is tested on the New England 39-bus system. As compared to a multilayer feed forward network (MFFN), the FCM-ANN yields better results in terms of accuracy and rapidity.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130658285","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 hybrid excited flux switching machine uses double excitations (permanent magnets and excitation coils) to control the flux linkage and the DC bus voltage. The design and the investigation of the electromagnetic performances have been effectuated on a 3 kW wind turbine equipped with hybrid excited flux switching machine. It is shown that the produced power can be easily controlled using the excitation current which is very interesting for wind turbine applications. According to the particular stator and rotor design, this presented machine is intrinsically safe in case of fault since no flux weakening is required.
