It is based on the interaction of the leakage inductance with the series inductance of the coupling capacitor. This effect is evident in sudden changes of the inductor currents during the switching processes, increases the electromagnetic interferences and decreases the efficiency of the converter. The theoretical analysis shows significant impacts, especially for closely coupled inductors. The impact and therefore the filter effort can be significantly reduced by optimizing the components and the PCB-layout. The effect is verified by means of LTSpice simulations and experimental measurements of a hardware setup. It is directly transferable to other higher-order converters.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"71 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":"124184773","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}

More specifically, considering a power grid an undirected graph, the proposed ‘division’ is based on vector cut sets of cardinality one.

In an effort to improve the compatibility of DLTs for the industrial informatics context, the authors developed a lightweight consensus for IIoT environments based off delegated proof of stake (DPoS), called Delegated Proof of Proximity (DPoP), to limit the processing and energy effort required by DLTs. DPoP will, however, require an existing, IIoT neighbour discovery process to facilitate a proof of proximity for the consensus process. Thus, this preliminary work aims to evaluate distance bounding as a possible mechanism for establishing a secure proof of proximity and neighbour discovery between nodes during the DPoP consensus process to improve the scalability and flexibility of DLT solutions, like Ethereum, for IIoT use cases.","PeriodicalId":194172,"journal":{"name":"2022 IEEE 31st International Symposium on Industrial Electronics (ISIE)","volume":"8 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":"114954714","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 order to overcome performance or operation reductions when facing latency peaks or temporary connection losses, we propose a predictive control method that generates control hypotheses, i.e. sampling, even for future steps. On the client device, the hypotheses are matched with current sensor readings if control commands fail to appear. In this publication, we focus on the efficient hypotheses matching on the client side and identify an adequate hashing approach for planar laser scanner data.

MPC requires more computation power in comparison to other controllers, such as PID or LQR, since it use cost functions, optimization methods and iteratively predicts the output of the system and the control commands for some determined steps in the future (prediction horizon). Thus, the computation power required depends on the prediction horizon, the complexity of the cost functions and the optimization. The more steps determined for the horizon the more efficient the controller can be, but also more computation power is required. Since sometimes robots are not capable of managing all the computing process locally, it is important to offload some of the computing process from the robot to the cloud. But then some disadvantages may occur, such as latency and safety issues. Cloud computing may offer “infinity” computation power but the whole system suffers in latency. A solution to this is the use of Edge Computing, which will reduce time delays since the Edge device is much closer to the source of data. Moreover, by using the Edge we can offload the demanding controller from the UAV and set a longer prediction horizon and try to get a more efficient controller.","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":"129934360","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 real-time harmonic monitoring is employed to indicate the development or existence of fault within the drive system. This is achieved by embedding a real-time measurement and control within the DSP operating in conjunction with the motor control, to estimate the machine's transient reactance after applying an excitation with voltage pulses using the switching of the inverter, and a real-time frequency analysis of the parameter within the FPGA operating independently of the motor control.

To achieve the same attenuation, it is possible to reduce the size of the interfacing filters by the usage of third-order filters; however, this kind of filtering comes with the limitation of having sustained oscillations caused by lack of damping especially during transient changes. Therefore, this work proposes, a methodology based on the principle of internal model to nullify these unwanted oscillations. The third-order system is modeled inside the microcontroller with the damping enabled. The error between the output from the model and the actual output are compared and the error is used to accomplish the active damping strategy.
