The voltage and current limits of VFRM, which depend on the current capacity of the inverter and the voltage limit of the inverter, are investigated by using MATLAB/Simulink. The d-axis and q-axis currents are represented using a mathematical model of VFRM. According to the analyses, the control algorithm for VFRMs is investigated in the field weakening region. VFRM can properly operate in the constant power region with this method. The conventional inverter is used to supply required d-axis and q-axis currents to armature windings with the space vector pulse width modulation (SVPWM) technique. The DC/DC converter is used to control field windings. For the validation of the investigated control algorithm, 12 slots, 10 poles VFRM is implemented in MATLAB/Simulink. The simulation results show that the investigated field weakening method for VFRM controls the motor in constant power region and extends the speed range.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85671557","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}

Feasibility of different treatments with cold plasma leads us today to design and realize various types and principles which allow to obtain such electrical discharges. All that are realized with different nominal parameters and with performances which are difficult to be evaluated and compared. Nowadays, the passing from treatment feasibility with cold plasma to the mass scale utilization of these treatments impose more and more characterization and performance evaluation of cold plasma reactors.

More than that, the standard V/f response in torque (and speed) remains slow and does not handle properly smaller loads at smaller current, in comparison with sensorless field oriented (FOC) or direct torque (DTC) control.Therefore, within the paper, a simplified sensorless control for fast torque (and speed) response based on V/f control, with two correction loops, one loop for the voltage amplitude correction, the other one for the voltage phase correction is proposed.

The performances of the dq-model, together with its control and electronic units, are evaluated through virtual tests. Furthermore, the model accuracy is validated by comparing the simulation results with the experimental data obtained from different tests performed on a Renault ZOE Q90 car. Two test scenarios, an urban test and a highway one, are chosen in order to evaluate the precision and the reliability of the developed model under normal and maximum electrical vehicle speed conditions.

When viewing fractal structures, is there a fractal complexity connection between the brain activity and the fractal visual stimuli? In this paper we investigate the possible correlations between the complexity of both the synthetic fractal images and the response EEG signals during the fractal images visualization. We present the results using two complexity metrics: entropy and fractal dimension. While for images, the spatial and color domains are considered, for EEG signals, the time domain with its amplitude characteristics and power spectral density information are analyzed. Even though no significant linear correlations are observed between the complexity of perceived images and the complexity of brain responses, various non-linear trends emerge.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83075256","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 calculation of the capacity is extracted from the high voltage waveform of the discharge, by measuring the frequency that appears when the discharge takes place.

This may be the case especially when the rotor is electrically connected to the earth potential of the system e.g. via the cogging wheels of a coupled gear. In this paper an axial bearing type 51208 is investigated at standstill and in rotation concerning the bearing resistance. The a-spot situations are estimated in standstill based on the measured signals. In rotation the bearing resistance is measured for a range of operating speeds from 0 rpm to 3000 rpm, a range of bearing currents from 0.5 A to 3 A, and two axial forces 180 N (rated condition), 800 N. A special test rig is designed to measure the bearing voltage and current signals without using mechanical brushes in the rotating system to eliminate the contact resistance of the brushes in the measured bearing signals. The results allow to predict the bearing electrical behavior at a bearing current flow through the ground.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88519923","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}
