Each inverter controller runs a basic clock which schedules all the real-time control tasks, according to the time-triggered paradigm. The clocks in the different inverters are kept in synchronism with each other, by applying a distributed clock synchronization algorithm. The inverter controllers are connected through two serial buses. The first bus is a TDMA serial bus exclusively dedicated to the interchange of the short and frequent control variables needed to enforce load sharing between inverters. Each inverter applies to these variables a fault-tolerant variant of the averaging load sharing control method. The second bus is a CAN bus, with time stamping of messages, used to interchange the clock synchronization messages and the low bandwidth supervision and control variables.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115828458","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 proposed switching function model is packaged in a graphical form to suit various simulation platforms such as Simulink and PSCAD. The validity of the presented model is confirmed using simulation and its scalability has been demonstrated on MMC with 301 cells per arm, considering power reversal during normal operation and dc short circuit fault.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"322 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115867265","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}

Multi-rate systems are used to simulate different part of the circuit with different sampling rate. This allows to reduce computational burden of stiff system; by choosing the most appropriate time-step according to the time constant of the phenomena studied. Traditionally, stability of discrete system is done by studying the eigenvalues of the system which can only uses a single sampling time and therefore cannot be applied to multi-rate systems. Many examples, where simulation is done with multiple rate, can be found in literature with no proof of stability other than simulation results. In this paper, multi-rate system are first represented as non-linear system using a single time-step and their stability is then demonstrated using Lyapunov's theorem. The proposed method is supported by a numerical example.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115616096","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 important role in this theory played hysteresis operator states. The changes of these operators' states are not immediate in the dynamic model but they are a function of time and parameter k representing the magnetic properties of the material. In this paper the transient state of the hysteresis operator is defined by the nonlinear first order differential equation. The implementation of the dynamic hysteresis is additionally associated with feedback hysteresis model. This allows for obtaining a more accurate model for low and high magnetization frequencies. The material parameter k was determined for the toroidal tape wound core made of anisotropic sheet steel ET114-27. This paper presents the magnetic hysteresis loop simulation results for the different magnetization frequencies.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129193339","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 specific inverter topology can be used after faulty inverter leg isolation from an electric motor under single IGBTs open-circuit faults. To overcome a significant problem related to the four-switch inverter topology, namely capacitor voltage unbalance in DC-link, a solution based on the voltages measurement was developed. In the proposed approach, depending on a motor drive operation point, in order to achieve a high drive performance a weighting factor of a cost function term related to capacitor voltages balance is adapted. To confirm the proposed method, simulation results were presented under a wide range working conditions of an induction motor drive system.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129956694","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 is the scope of the PROTACTICAL project, which the main goal is to ensure the QoS requirements in critical applications (First Responder) through exploitation of fading characteristics of on-body channel and external interference RF of coexistent systems and devices in real scenarios.

In conventional AC drives, this converter requires an input multipulse transformer, which allows the low frequency harmonic cancellation that are generated by the three-phase diode rectifiers included in each cell. This multipulse transformer is bulky, heavy, expensive, and must be designed according to the number of power cells, making the transformer topology dependent. This work proposes and evaluates a harmonic minimization strategy based on a Finite Control Set - Model Predictive Control (FCS - MPC), which emulates the harmonic cancellation of a multi-pulse transformer. This feature allows the minimization of the Total Harmonic Distortion (THD) of the AC grid current of the multi-cell converter. The evaluation is focused in one disadvantage of the FCS - MPC which is its high switching frequency that causes high losses in the semiconductors. To overcome this disadvantage, an additional objective function is proposed. Simulation results prove the theory, with satisfactory results.","PeriodicalId":156295,"journal":{"name":"2015 IEEE International Conference on Industrial Technology (ICIT)","volume":"134 2-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114464255","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}

To correctly regulate the average current value, as well as to simplify the system model, the controller must include a ripple filter. The proposed system includes a new low-phase-lag ripple filter. The whole system is first modelled in the s-domain to easily include the plant dynamics. The validity of the s-domain analysis up to half the switching frequency, once the controller is converted into the z-domain, has been verified by simulating its frequency response and its transient behavior.
