The number of weighting factors is greatly reduced in comparison to conventional model predictive torque control. Three cost functions are evaluated in sequential manner to control the total torque and direct-axis currents. In the proposed method, the control performances can be adjusted by changing the selection criteria of the candidate voltage vectors, while it is done by tuning the weighting factors in conventional PTC. Simulation results have shown that, with the proposed method, predictive torque control of multiphase motor drives can be realized in a more simple and flexible way.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"38 38","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120812879","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 Europe, as well as in the US, around 10% of all employees work in this sector. Macro economic studies estimate that in general 47% of all jobs will be automated due to digitalization. FS will be highly affected by the megatrend digitalization as numerous routine tasks are performed in this sector. However, current studies only provide a macroeconomic view on the changes. Therefore, this paper aims to answer the following research questions: Which smart building technologies are relevant for FS? Which are already in use and which services will be affected? The basis for the current research was a qualitative prestudy. Fifty German speaking Facility Managers were asked about the technical and economic feasibility of smart building technologies in the FS sector. Based on the smart building technologies identified as relevant, the authors carried out a quantitative literature review. This analysis did not only include publications about the usage of smart building technologies in the FS industry, but also considered use cases on the technologies identified by the pre-study in other industries. In total, more than 350 cases were analyzed. Based on that literature review, a research database was set up to explore the relevant technologies and the affected services in detail. The next research step was to compare the results of scientific publication with those of commercial studies and the results of the pre-study. Thus, this paper outlines the relevant technologies and FS. It further presents the detailed results of the validation process.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"2007 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127303820","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}

This two battery HEECS de/de chopper shows a very high efficiency over 99%, based on the principle of a partial power conversion [1]. However, if SOC's of two batteries in this chopper do not become zero at the same time, the chopper may not work well and as a result, the vehicle can no longer run. As a solution of this problem, the soft SOC balancing method for two batteries on HEECS is proposed, in which any hard ware is required, and by the control algorithm the SOC's will be balanced. Simulation results showed that SOC's unbalancing can be solved by changing de/de chopper duty ratio from PWM to fixed duty depending on SOC's of two batteries. Based on this proposal, the driving distance can be extended 7.6 % under 10–15 driving mode test cycles. The validity of the proposal soft balancing technique was verified under another three types of driving mode cycles such as JCOS, Worldwide harmonized Light vehicles Test Cycle (WLTC) mode Low speed phase, and WLTC mode Medium speed phase.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124786013","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}

This software approach was designed for use in an IoT environment, with special emphasis on smart homes. Thus, serving as a basis to support information exchange. The Smart Comm was developed in a scenario architecture adopting microservices. As a result, the communication between the gateway and IoT devices can be done considering a peer communication. This procedure can also be observed in the exchange information between Smart Comm. Therefore, bringing security, scalability and the flexibility to handle the variety of devices.

In this work the use of OFDM (Orthogonal Frequency Division Multiplexing) modulation was evaluated in the new generation optical networks. As proof of concept, the performance of optical networks in different configurations was analyzed using OptiSystem Software®. Some advantages and disadvantages of the use of OFDM modulation for the next generation networks were evidenced.

On the other hand, complexity of the control increases significantly, since the condition on each electric motor can vary in a wide range. Today, majority of control algorithms are based on field oriented control. The consequences of parallel connection of induction motors are addressed by prioritizing model of the motors with higher relevance to the control. The control problem becomes even more complicated when the drive is equipped with common sensors measuring phase currents at the inverter output only. Performance of the field oriented control strongly depends on the model with full state, which is not available trough measurement, due to the lack of current sensor for particular motors. We propose to simplify the model of dual motor drive and use it with finite control set model predictive control (FCS-MPC). The steady state solution of the control problem is used to improve the control performance. This is achieved as an additional term in the cost function. The algorithm is designed with respect to maximum simplicity and its properties are tested in simulations as well as in a real experiment on the laboratory prototype of a dual induction motor drive of rated power $2mathrm{x}4.5$ kW.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126011402","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}
