基于社会网络分析的新能源汽车电机控制系统态势分析

Situation Analysis of New Energy Vehicle Motor Control System Based on Social Network Analysis

本文利用文献计量法和社会网络分析研究新能源汽车电机控制系统的相关发展现状和近些年来的研究热点。对2010-2021年间的中国知网数据库在该研究领域的文献发表年份、关键词共现图谱、作者合作网络等内容进行分析。结果表明,近十年研究新能源汽车的发文数量在波动中呈总体上升趋势;形成了多个研发团队,内部合作紧密;主要的研发方向为永磁同步电机、滑膜控制、容错控制、模型预测控制、动力电池、定子电阻估计器、自抗扰控制等。其中滑膜控制、容错控制、模型预测控制等属于新能源汽车电机控制的内容,本文重点就电机控制系统近些年的研究热点进行分析。

This paper uses bibliometrics and social network analysis to study the relevant development status of new energy vehicle motor control systems and the research hotspots in recent years.Analyze the publication year,keyword co-occurrence map,author cooperation network and other contents of the CNKI database in the research field from 2010 to 2021.The results show that the number of publications on new energy vehicles in the past ten years has shown an overall upward trend in fluctuations;multiple R&D teams have been formed with close internal cooperation;the main R&D directions are permanent magnet synchronous motors,sliding film control,fault-tolerant control,and models Predictive control,power battery,stator resistance estimator,active disturbance rejection control,etc.Among them,sliding film control,fault-tolerant control,model predictive control,etc.belong to the content of new energy vehicle motor control.This article focuses on the analysis of the research hotspots of motor control systems in recent years.
