To improve the stability of the fuel cell converter, an adaptive finite-time controller is proposed in this paper, which not only has stronger robustness but also realizes the large-signal stability of the fuel cell converter. Firstly, considering the load uncertainty, the canonical form of fuel cell converter is obtained by coordinate transformation, and the nonlinear model of fuel cell stack and converter is derived. Secondly, the disturbance observer is used to observe the load variation to ensure that the output voltage of the converter can accurately track the reference value. Thirdly, because the fuel cell output voltage is determined by the load power, a fuel cell output voltage estimator should be designed to estimate the real-time output voltage of fuel cell. Finally, the robustness and effectiveness of the control algorithm are verified by simulations.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132616487","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}

For terminal voltage control, a four-leg voltage source inverter (VSI) is employed. The VSI system also provides harmonic and neutral currents compensation while the SEIG system is feeding 1-ϕ and 3-ϕ loads. For generation frequency control, the SEIG system uses an adjustable speed induction motor drive (ASIMD) system coupled to a water pumping mechanism. The ASIMD system acts like an auxiliary load and consumes the power in excess of the actual loads in order to regulate the system frequency. The power absorbed by the ASIMD system is utilized in water pumping applications. A third order pre-filter (TOPF)-based control algorithm is proposed for the control of the VSI system. The ASIMD system uses direct torque control (DTC) to achieve adjustable speed control. The performance of the SEIG-based autonomous power system with the proposed control is demonstrated using experimental results.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"10 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132784220","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 loads need continuity of power supply when the network is in islanding mode due to various events such as short circuit faults. The existence of at least one DG in these networks is necessary. In this paper, the proposed method is applied to the IEEE 33-bus distribution network in two connection modes.

To logical manage this trouble, the presented paper proposes a new lossy data compression approach for big data compression. In the proposed method, at the first step, the optimal singular value decomposition (OSVD) is applied to a matrix that achieves the optimal number of singular values to the sending process and the other ones will be neglected. This goal is done due to the quality of retrieved data and the rate of compression ratio. In the presented scheme, to implementation of the optimization framework, various intelligent optimization methods are used to determine the number of optimal values in the elimination stage.

A BMS with a good SOC assessment can dramatically improve the lifespan of the battery and ensure the safety of the end-user. With deep learning making tremendous strides in many other fields, this study aims to provide an empirical evaluation of commonly used deep learning methods on the task of SOC estimation. We propose the use of two-hidden-layer gated recurrent units (GRU) to estimate the SOC at various ambient temperatures. In this work, we conducted two experiment setups to showcase the capability of the proposed GRU model. In the first setup, the GRU was trained on the DST, BJDST and US06 drive cycle and evaluated the FUDS drive cycle upon convergence. The same procedure was repeated with the second setup except the GRU was trained on the DST, BJDST and FUDS drive cycle and evaluated on the US06 drive cycle. In both experiment setups, the proposed GRU was evaluated on a novel drive cycle that it has not encountered during the training phase. We show that a two-hidden-layer GRU with appropriate hyperparameter combination and training methodology can reliably estimate the SOC of novel drive cycles at various ambient temperatures in comparison with other deep learning methods such as simple recurrent network (SRNN), Long Short-Term Memory (LSTM), 1D Residual Network (Resnet), 1D Visual Geometry Group Network (VGG) and the Multilayer Perceptron (MLP). The proposed GRU achieves 2.3% RMSE on the FUDS drive cycle and 1.2% RMSE on the US06 drive cycle outperforming all other models.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114699498","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 flux density distributions of end structural components, such as finger plate, clamping plate, magnetic shield and metal shield, are calculated with different materials of metal shield under the rated excitation and 3.5 times rated excitation. The flux density of the key zones on the end structural components are compared and analyzed. In addition, the loss distributions of the end structural components are calculated and compared in three cases. The influence of different metal shield materials on losses of the end region is studied, and the end structural component that has the maximum loss is obtained.

The dynamic model of voltage source converter (VSC) controller is developed, considering distributed droop control scheme. Besides, to track the dynamic behaviors of the system, an extended Kalman filter (EKF) algorithm is employed to derive dynamic state estimation (DSE).

ASMHC approach includes the sliding-mode controller (SMC), robust H∞ controller, and SEFLIT2PFNN estimator. In ASMHC design, the SMC technique is employed as it has rapid dynamic response with an invariance capability against uncertain dynamics, SEIT2FLFNN estimator is utilized for approximating the uncertain nonlinear functions of the X-Y table and the H∞ controller is developed for compensating the effects of the SEFLIT2PFNN approximation errors and external disturbances at a definite attenuation level. Furthermore, H∞ control theory and Lyapunov stability analysis are employed for online adaptive control laws, so that the stability of the ASMHC scheme can be assured. The validity of the proposed control system is verified by experimental analysis. The dynamic response of the X-Y table motion control system using ASMHC promises closed-loop stability and promises the H∞ tracking performance for the whole system.
