This type of converters is used in sustainable energy generation and it is suitable for the electrical vehicle application. The three-phase dual active bridge dc-dc converter consists of two power conversion stages (an inverter and a rectifier) separated by three single phase high frequency planar transformers in order to provide a galvanic isolation between the input and the output. A phase shift control strategy is applied between the signal gates of the switches of the two active bridges in aims to control the transferred active power from the input port to the output. Thanks to the three-phase structure and the high frequency operation, this system is characterized by low input current ripples and it has the advantage of its reduced size. Moreover, this converter provides a high voltage gain and a wide input voltage range with an important efficiency. In this paper, the modeling and the control of the dual active bridge dc-dc converter will be clearly explained and simulations results under MATLAB/SIMULINK will be shown to validate the operation of the converter topology. Finally, detailed analysis will be carried out.","PeriodicalId":250315,"journal":{"name":"2020 4th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115961287","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 linearization method is used to cast the problem from the impulsive hybrid nonlinear dynamics into the linear dynamics around a desired one-periodic hybrid limit cycle of the PDW. Thus, using the first-order Taylor approximation, we design an explicit expression of the controlled Poincaré map. In order to control the passive gaits, we develop first the linearized Poincaré map obtained around the period-one fixed point. We adopt a state-feedback control law using the LMI approach to stabilize this fixed point. We present finally some simulation results to reveal the efficiency of the designed control law in the control of the passive-dynamic locomotion of the compass-gait biped robot.","PeriodicalId":250315,"journal":{"name":"2020 4th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122101443","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 versions of the obtained hardware modules can be loaded according to the requirements of the application in different possible Partial Reconfigurable Region (PRR) in the FPGA circuit. The objective is to optimize the hardware resources by adapting each PRR to the size of the hardware task. A partitioning adapted to the different scenarios and versions of the implemented modules has been proposed.

The objective of this paper is to study the harmonic distortion in view of a micro lighting network. More specifically, the tested 250W HPS lamps, with magnetic ballast, are evaluated and provided with the adequate compensation. The interesting features of the adopted filtering method are performance, predictability and reliability to reduce the harmonic distortion problem, the operating and design of the compensator parallel active filter “PAF” are presented. The obtained results by this parallel active filter satisfy both the harmonic distortion correction and the power factor compensation, a good improvement in the stability and precision of the signal waveform and in power quality are presented.

First, the modeling and the control of the system using the terminal sliding mode and the model free algorithms were made. Then, a combination between these two controllers was done to get the new model free terminal sliding mode approach. A stability study is realized.

Zero-Forcing Max-Power Beamforming for Hybrid mmWave Full-Duplex MIMO Systems 混合毫米波全双工MIMO系统的零强迫最大功率波束形成

In the context of 5G technology, FD systems operating at millimeter-wave (mmWave) frequencies become one of the most promising solutions to further increase the spectral efficiency and reduce the latency. However, such systems are vulnerable to the self-interference (SI) that significantly degrades the performance. To overcome this shortcoming, analog-only beamforming techniques have been developed to mitigate the SI. Because of the huge power consumption, systems operating at mm Wave frequencies beamform the power by only tuning the phase shifters while maintaining constant amplitudes. Such a hardware constraint, known as the constant amplitude (CA) constraint, severely limits the system performance. In this work, we propose a digital and analog hybrid beamforming design that completely eliminates the SI while substantially minimizing the losses imposed by the CA constraint. Further, we develop a fully-digital beamforming design and derive the upper bound for the spectral efficiency as benchmarking tools to quantify the losses of our proposed hybrid design.","PeriodicalId":250315,"journal":{"name":"2020 4th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128501841","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}
