| 1 | A survey of web resources and tools for the study of TCM network pharmacology显示文摘Background: Traditional Chinese medicine (TCM) treats diseases in a holistic manner, while TCM formulae are multi-component, multi-target agents at the molecular level. Thus there are many parallels between the key ideas of TCM pharmacology and network pharmacology. These years, TCM network pharmacology has developed as an interdisciplinary of TCM science and network pharmacology, which studies the mechanism of TCM at the molecular level and in the context of biological networks. It provides a new research paradigm that can use modern biomedical science to interpret the mechanism of TCM, which is promising to accelerate the modernization and internationalization of TCM? Results: In this paper we introduce state-of-the-art free data sources, web servers and softwares that can be used in the TCM network pharmacology, including databases of TCM, drug targets and diseases, web servers for the prediction of drug targets, and tools for network and functional analysis. Conclusions: This review could help experimental pharmacologists make better use of the existing data and methods in their study of TCM. | Jing Zhao Jian Yang Saisai Tian Weidong Zhang | 2019 | Frontiers of Electrical and Electronic Engineering in China2019，7，1： | 17 |

| 6 | An Optimal Coordination Control Strategy of Micro-Grid Inverter and Energy Storage Based on Variable Virtual Inertia and Damping of VSG显示文摘The virtual inertia and virtual damping affect both the dynamic stability of the virtual synchronous generator(VSG)and the configuration of energy storage,but there is a conflict between them while selecting the virtual inertia and virtual damping.An optimal coordination control strategy of micro-grid inverter and energy storage based on variable virtual inertia and damping is proposed to mitigate this conflict.With the integrated optimal constraint of the VSG frequency variation and the energy storage capacity,the virtual inertia and damping of VSG are configured dynamically,adopting linear quadratic optimal control.It can suppress the oscillations of the active power and frequency to improve the stability of VSG and optimally configure the energy storage capacity of VSG simultaneously.The proposed strategy aims to improve the control performance of micro-grid inverter and the system economy.The simulation and experimental results verify the effectiveness of the strategy. | Xing Zhang Fubin Mao Haizhen Xu Fang Liu Ming Li | 2017 | Chinese Journal of Electrical Engineering2017，3，3： | 10 |
| 7 | Performance Evaluation of Two-Vector-Based Model Predictive Current Control of PMSM Drives显示文摘Conventional model predictive current control(MPCC)applies only one vector during one control period,which produces large torque and flux ripples and high current harmonics in permanent magnet synchronous motor(PMSM)drives.Recently MPCC with duty cycle control has been proposed to improve the steady state performance by applying one non-zero vector and one null vector during one control period.However,the prior method requires lots of calculations and predictions to find the optimal voltage vectors and calculate their respective duration.Different from prior enumeration-based MPCC,this paper proposes an efficient two-vector MPCC by applying two arbitrary voltage vectors during one control period.The reference voltage vector is firstly calculated based on the principle of deadbeat current control.Two optimal vectors and their duration are then obtained in a very efficient way,which does not require the calculation of current slopes in prior MPCC methods.The proposed method is compared to the state-of-the-art predictive control methods,including conventional MPCC,MPCC with duty cycle control,deadbeat control with space vector modulation(SVM)and modulated model predictive control(M2PC).Both simulation and experimental results prove that the proposed method achieves better steady state performance than conventional MPCC with or without duty cycle and the dynamic response is not degraded.Under the condition of insufficient dc bus voltage,the proposed method outperforms deadbeat control and M2PC by presenting even higher speed range and less torque ripples. | Yongchang Zhang Lanlan Huang Donglin Xu Jiali Liu Jialin Jin | 2018 | Chinese Journal of Electrical Engineering2018，4，2： | 9 |

| 9 | Predicting enhancer-promoter interaction from genomic sequence with deep neural networks显示文摘Background:In the human genome,distal enhancers are involved in regulating target genes through proximal promoters by forming enhancer-promoter interactions.Although recently developed high-throughput experimental approaches have allowed us to recognize potential enhancer-promoter interactions genome-wide,it is still largely unclear to what extent the sequence-level information encoded in our genome help guide such interactions.Methods:Here we report a new computational method (named 'SPEID') using deep learning models to predict enhancer-promoter interactions based on sequence-based features only,when the locations of putative enhancers and promoters in a particular cell type are given.Results:Our results across six different cell types demonstrate that SPEID is effective in predicting enhancerpromoter interactions as compared to state-of-the-art methods that only use information from a single cell type.As a proof-of-principle,we also applied SPEID to identify somatic non-coding mutations in melanoma samples that may have reduced enhancer-promoter interactions in tumor genomes.Conclusions^ This work demonstrates that deep learning models can help reveal that sequence-based features alone are sufficient to reliably predict enhancer-promoter interactions genome-wide. | Shashank Singh Yang Yang Barnabas Poczos Jian Ma | 2019 | Frontiers of Electrical and Electronic Engineering in China2019，7，2： | 8 |

| 11 | Influence of Magnet Shape on the Cogging Torque of a Surface-mounted Permanent Magnet Motor显示文摘The influence of bread-loaf shaped magnet poles under parallel magnetization on the cogging torque of surface-mounted permanent magnet(SPM)motors is studied.For the SPM motors having magnetic poles with eccentricity and sine harmonic compensation,the electromagnetic performances of integer and fractional slot motors are compared.It is found that the cogging torque and torque ripple of the integer and fractional slot motors can be reduced with the same eccentric magnet pole.The cogging torque and torque ripple of a fractional slot motor can be decreased by sine harmonic compensation,however,the same sine harmonic compensation has a small influence in integer slot motors.By varying the magnetic poles,the contribution of the field harmonics(k=(2n+1)p),which are a direct result of magnet magnetization,to the cogging torque also changes.The electromagnetic performance of a 3 kW prototype is tested,and it is found that the experimental results validate the theoretical investigation. | Min Zhou Xinxing Zhang Wenxiang Zhao Jinghua Ji Jingning Hu | 2019 | Chinese Journal of Electrical Engineering2019，5，4： | 7 |

| 13 | Underwater map-matching aided inertial navigation system based on multi-geophysical information显示文摘In order to achieve long-term covert precise navigation for an underwater vehicle,the shortcomings of various underwater navigation methods used are analyzed.Given the low navigation precision of underwater mapmatching aided inertial navigation based on singlegeophysical information,a model of an underwater mapmatching aided inertial navigation system based on multigeophysical information(gravity,topography and geomagnetism)is put forward,and the key technologies of map-matching based on multi-geophysical information are analyzed.Iterative closest contour point(ICCP)mapmatching algorithm and data fusion based on Dempster-Shafer(D-S)evidence theory are applied to navigation simulation.Simulation results show that accumulation of errors with increasing of time and distance are restrained and fusion of multi-map-matching is superior to any single-map-matching,which can effectively determine the best match of underwater vehicle position and improve the accuracy of underwater vehicle navigation. | Zhongliang DENG Yuetao GE Weiguo GUAN Ke HAN | 2010 | Frontiers of Electrical and Electronic Engineering in China2010，5，4： | 6 |

| 15 | Open-circuit Fault Diagnosis of Traction Inverter Based on Compressed Sensing Theory显示文摘This study proposes a new method of fault diagnosis based on the least squares support vector machine with gradient information(G-LS-SVM)to solve the insulated-gate bipolar transistor(IGBT)open-circuit failure problem of the traction inverter in a catenary power supply system.First,a simulation model based on traction inverter topology is built,and various voltage fault signal waveforms are simulated based on the IGBT inverter open-circuit fault classification.Second,compressive sensing theory is used to sparsely represent the voltage fault signal and make it a fault signal.The new method has a high degree of sparseness and builds an overcomplete dictionary model containing the feature vectors of voltage fault signals based on a double sparse dictionary model to match the sparse signal characteristics.Finally,the space vector transform is used to represent the three-phase voltage scalar in the traction inverter as a composite quantity to reduce the redundancy of the fault signals and data-processing capabilities.A G-LS-SVM fault diagnosis model is then built to diagnose and identify the voltage fault signal feature vector in an overcomplete dictionary.The simulation results show that the accuracy of this method for various types of IGBT tube fault diagnosis is over 98.92%.Moreover,the G-LS-SVM model is robust and not affected by Gaussian white noise. | Yongqi Cheng Weiguang Dong Fengyang Gao Guoqing Xin | 2020 | Chinese Journal of Electrical Engineering2020，6，1： | 6 |
| 16 | Delay-dependent Robust Stability Analysis of Power Systems with PID Controller显示文摘This study examines the robust stability of a power system,which is based on proportional-integral-derivative load frequency control and involves uncertain parameters and time delays.The model of the system is firstly established,following which the system is transformed into a closed-loop system with feedback control.On this basis,a new augmented Lyapunov-Krasovskii(LK)functional is established for using the new Bessel-Legendre inequality to estimate the derivative of the functional,which can provide a maximum lower bound.A stability criterion is then derived by employing the LK functional and Bessel-Legendre inequality.Finally,numerical examples are used to demonstrate the validity and superiority of the proposed method. | Li Shen Huiqin Xiao | 2019 | Chinese Journal of Electrical Engineering2019，5，2： | 6 |
| 17 | Active Power Reserve Photovoltaic Virtual Synchronization Control Technology显示文摘The photovoltaic virtual synchronous generator(PV-VSG)solves the problem of lack of inertia in the PV power-generation system.The existing PV plants without energy storage are required to participate in the power grid’s frequency modulation(FM),but existing PV-VSGs with energy storage have high requirements for coordinated control.Therefore,the active power reserve PV-VSG(APR-PV-VSG)is studied.Based on the different methods to obtain the maximum power point(MPP),the peer-to-peer and master-slave APR-PV-VSG strategies are proposed.The PV inverters are deviated from the MPP to reserve active power,which is used as the virtual inertia and primary FM power.These methods equip the PV power station with FM capability.The effectiveness of the proposed control strategies is verified by simulation results. | Xing Zhang Qian Gao Yuhua Hu Haizheng Zhang Zixuan Guo | 2020 | Chinese Journal of Electrical Engineering2020，6，2： | 6 |

| 20 | A 2-D Fuzzy Logic Based MRAS Scheme for Sensorless Control of Interior Permanent Magnet Synchronous Motor Drives with Cyclic Fluctuating Loads显示文摘Model reference adaptive system(MRAS)is typically employed for rotor position/speed estimation in sensorless interior permanent magnet motor(IPMSM)drives.The adjustment of control parameters in MRAS is a key issue for IPMSM drive systems with cyclic fluctuating loads.In order to avoid the difficulties involved with manual tuning of the control parameters,a new MRAS scheme based on fuzzy logic is proposed in this paper in which a fuzzy controller replaces the conventional PI regulator.To implement this new MRAS scheme,a two-dimensional(2-D)fuzzy rule is designed.The proposed control scheme is employed in the IPMSM drives with cyclic fluctuating loads such as compressors.In order to lower the motor speed ripple caused by the cyclic fluctuating load,a feed-forward compensation strategy with the load-matching motor output torque pattern is developed.Experimental results demonstrate the feasibility and effectiveness of the proposed fuzzy logic based MRAS scheme with minimal rotor position estimation error. | Yang Mei Kai Sun Yuchao Shi | 2015 | Chinese Journal of Electrical Engineering2015，1，1： | 6 |
