The control law is based on modifying the permeance of ferrite-cores for Variable-Transformers (VT). The frequency-domain model of the VT control leg is obtained using the Gyrator-Capacitor theory. Finally, this model is found by the premise that the interactions of the transformer's main fluxes are minimum in the control leg. Furthermore this paper also proposed a ferrite-core construction that reduces these interactions, thereby minimizing the induced voltage in the control winding, implying the parallel interactions of the fluxes are reduced. The results indicate that the perturbations are manageable for the control scheme and do not affect the device operation.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123055002","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 1735 Fluke power logger unit and the Fluke 59 mini-infrared thermometer are respectively used for total load current and ambient temperature recordings. The ANFIS, such as implemented in MatLab R2019b software package, is invoked to perform 24-hour computation and subsequently predict the status of insulation life for 7 consecutive days based on 24-hour measurement of the load current, ambient temperature and the hottest-spot temperature.

The best classification method for the galvanic skin response sensor and the current sensor of the electric traction motor is determined. Fine kNN (fine k-nearest neighbors) is the most successful classification method for the galvanic skin response sensor data and the artificial neural network is the most successful method for the current sensor data. In the second part of the study, the driving confidence of the drivers is elaborated around the road junctions where the driver has to detect and prevent possible hazards. Logged data of the galvanic skin sensor, current sensor and velocity measurement is analyzed to monitor the confidence level while approaching and passing two junctions on the pre-specified route. In the third part of the study, based on the GSR sensor measurement, electric motor torque is intervened when a deviation between the average value and measured value. An experimental setup including the RFID card containing the average skin conductivity of each driver is presented.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121057934","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 data-driven representation of the system is done through the concept of SmartData, a data construct that includes concepts of location, timing, and semantics, providing an alternative to represent critical systems through the data they rely on. The timing and dependency relationship between different SmartData are derived into an STL expression that specifies the property monitors to verify each piece of data. The same verification is also presented in the form of timed automata, a closer representation of the tools adopted for runtime verification. The SmartData representation and STL and timed automata models are depicted through a case study considering an autonomous vehicles application.

Other than enhanced energy economy, a proper energy management system must guarantee acceptable driving comfort, compliance with the allowed battery state-of-charge window, and on-board computational efficiency. While several studies from the literature have compared different state-of-the-art real-time HEV powertrain energy management strategies, not much work has been performed on the hardware-in-the-loop (HIL) assessment of these control approaches. This paper aims at answering the identified research need by performing an experimental HIL assessment of different state-of-the-art HEV control strategies including a rule-based control (RBC) approach and three different formulations of equivalent consumption minimization strategy (ECMS), both of traditional and adaptive type. A parallel-through-the-road HEV is considered for this case study. Various assessment criteria are retained including HEV fuel economy, measured computational time, and comfort of the ride in terms of frequency of de/activation events and smoothness of the controlled value of torque over time for the internal combustion engine. Obtained results suggest that the RBC approach can achieve improved performance in almost all the retained evaluation criteria. The traditional ECMS can outperform RBC in terms of fuel economy, yet by undermining both ride comfort and compliance with the battery SOC window. Finally, an adaptive ECMS can outperform the RBC in terms of fuel economy while ensuring acceptable comfort and compliance with the battery SOC window, yet at a significant computational cost increase.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126767991","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 cause of this requirement is the need for regulatory compliance, safety of equipment, and protection of workers and consumers. Smart metering is a key component of smart grids and smart metering data creates avenues to address this issue. Algorithmic methods to identify solar PV generation from consumption data will allow DNOs to maintain up to date knowledge of their networks allowing them to address any issues of safety or compliance. In this paper we investigate if classification of smart metering electricity consumption daily load profiles as solar or non-solar is possible with decision tree classifiers. We compare decision trees on our data after different forms of preprocessing are applied. We then apply this approach to smart metering datasets of solar and non-solar customers and show the ability to classify solar PV daily load profiles with up to 92% accuracy. This contributes to the knowledge about smart metering data analytics methods that can be used by smart grid stakeholders.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122601509","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}
