课题研究方向一般是指学生在校期间，或者相关科研工作者在申报撰写论文过程中需要明确的研究方向。课题研究方向应在所研究课题历史基础上提出自己独特或者有所创新的研究方向以丰富学科知识体系。论文题目由教师指定或由学生提出，经教师同意确定。均应是本专业学科发展或实践中提出的理论问题和实际问题。通过这一环节，应使学生受到有关科学研究选题，查阅、评述文献，制订研究方案，设计进行科学实验或社会调查，处理数据或整理调查结果，对结果进行分析、论证并得出结论，撰写论文等项初步训练。扩展资料：注意事项1、研究课题的基础工作——搜集资料。考生可以从查阅图书馆、资料室的资料，做实地调查研究、实验与观察等三个方面来搜集资料。搜集资料越具体、细致越好，最好把想要搜集资料的文献目录、详细计划都列出来。2、研究课题的重点工作——研究资料。考生要对所搜集到手的资料进行全面浏览，并对不同资料采用不同的阅读方法，如阅读、选读、研读。3、研究课题的核心工作――明确论点和选定材料。在研究资料的基础上，考生提出自己的观点和见解，根据选题，确立基本论点和分论点。参考资料来源：百度百科-毕业论文

研究方向和选题范围可以是和你专业方向有关的，如物流专业的话可以选择“库存管理中的零库存”“采购管理之供应商管理”作为论文的方向，研究方向和选题范围最好细化一些，不要选太大的题，太大太泛的题老师往往觉得不好，并且最好选跟自己本专业相关的题目，虽然你也可以选别的专业的题目。

一般学校里面带毕业论文的老师都有自己特定的课题，你可以选择自己喜欢、感兴趣的去做，如果没有你喜欢的，可以自己设置一个题目，经学校批准，自己做，不过这样导师可能无法在内容上指导你，仅能在做课题的一般方法上给予你指导。以上是作为过来人的个人意见，仅供参考！

要考虑自己的能力和时间要求，智能制造相对来说更宏观一些，内容更广一些，而智能控制技术相对来说要精细一些，内容更深一些。论文选题可遵循以下几条原则：选择自己所学专业范围之内，体现专业素养，综合考虑自己的能力和时间要求，选题选择大小适中，所选题目与生活相关，通过研究帮助解决现实中的问题。智能制造，源于人工智能的研究，一般认为智能是知识和智力的总和，前者是智能的基础，后者是指获取和运用知识求解的能力。智能控制是具有智能信息处理、智能信息反馈和智能控制决策的控制方式，是控制理论发展的高级阶段，主要用来解决那些用传统方法难以解决的复杂系统的控制问题。

Abstract: With the development of power electronics technology， harmonic hazards has become increasingly serious， harmonic governance issues has been On the power source for electronic devices harmonic analysis and concluded that its harm and the corresponding harmonic management principles and comprehensive management， and management of a harmonic Key words: power electronics; harmonics; hazards; inhibition INTRODUCTION With the development of power electronics technology， power electronic devices to the extensive application of power system harmonics caused serious Various power electronic equipment in the transport， metallurgical， chemical and other industrial traffic the extensive application of harmonics in the grid problem is becoming increasingly serious， many low power factor of power electronic devices to the power grid additional burden on the quality of power and influence， Therefore， the power electronic devices harmonic pollution has become hinder the development of power electronics technology major Therefore， inhibition harmonic pollution and improve the power factor of power electronics technology has become a major issue in This paper focus on the key issues of power through electronic harmonic sources and the danger of understanding and analysis， and control of pollution from the relationship between the consideration of a comprehensive management approach on the final harmonic trends in the development of comprehensive management of the A power electronic device - the main source of harmonics Nonlinear load is a harmonic sources， which caused grid voltage distortion， in the voltage several times with the whole of the fundamental frequency Harmonic as the main source of power for various electronic devices mainly AC-DC converter (rectifiers， inverters， chopper， Drives)， as well as bidirectional thyristor controlled switching equipment， as well as internal power system Variable Flow equipment， such as HVDC rectifier valve and the valve， and other Below its harmonics generated an analysis of the 1 Rectifier As a DC power supply devices， rectifiers widely used in various Figure 1 (a) and Figure 1 (b) respectively for the single-phase and three-phase circuits In rectifier devices， AC power supply for the current rectangular wave， rectangular wave of the fundamental frequency for the current and Jibeiai several times for the high-frequency harmonic current waveform Obtained by Fourier series of rectangular wave of high harmonics In fundamental component I1 and the largest ratio of 1 / n， with the trigger control angle α， and the decrease of overlap angle μ for the increase of harmonic wave components have reduced In addition， the existing research results indicate that: Rectifier harmonic current operation mode of the size， has a direct impact， therefore consider adjusting the voltage and current rectifier， it is best to conduct overlap angle， as well as for harmonic phase pressure drop calculations， in order to determine safe and economical operation mode when the control close to 40 ° angle α， overlapping in the 8 ° angle μ about the circumstances are often the most serious state of harmonic， so to go through， as far as possible through the correct choice of regulating transformers tap in order to avoid Harmonic most serious point [1] 2 exchange regulator Exchange regulator used for lighting dimming and induction motor speed， and so Figure 2 (a) and 2 (b) respectively for the single-phase and three-phase circuits Exchange regulator and the harmonic frequency rectifier basically the Frequency Converter 3 Frequency converter is AC / AC Converter behalf of equipment， when used as motor speed control devices， which contain a change with the output frequency band edge， as for the frequency change， the more complicated harmonic Universal Converter 4 GM converter input circuits are all from the diode bridge rectifier and DC capacitor components in Figure 3 (a) shows， this circuit impedance input current waveform with the different big In the source impedance relatively small cases， the waveform for the lanky Zhaier high-waveform in Figure 3 (b) solid line shows the contrary， when the source impedance relatively large， its waveform for the dwarf and wide flat waveform Figure 3 (b) shown in dotted In addition to these typical converter will be a great number of harmonics， household appliances is not to be ignored harmonic Such as television sets， battery Although their individual capacity little， but because a lot of volume， they injected into the power supply system to the harmonic components can not be 2 harmonic hazards Harmonic hazards of the public network include: 1) make a public network components have additional harmonic loss and reduce the power generation， power transmission equipment efficiency， a large number of 3rd harmonic flow neutral line， the line will cause overheating or even a fire; 2) impact of the normal work of electrical equipment， in addition to additional wear and tear caused， and also enable a motor mechanical vibration， noise and over-voltage， transformer partial serious overheating， capacitors， cables and other equipment overheating， insulation aging， shortened life expectancy， resulting damage; 3) common cause in the local power grid and parallel resonant series resonance， so that harmonic magnification so that the aforementioned hazards greatly increase， or even lead to serious accidents; 4) will lead to protection and automatic device misoperation， and electrical measuring instrument measurement inaccurate; 5) to neighbouring interfere with communications systems， light， noise and lower the quality of communication， information led to heavy loss of the communications systems do not work 3 harmonic management principles To improve power quality， we must strengthen the management of the In restricted to the utility grid harmonic source harmonic current injection， will be allowed to limit the harmonic voltage within the scope of the First it is necessary to have systems in the harmonic sources and distribution， in the harmonic limit its scope in order to allow access， not curing the management measures must be taken to prevent the spread of For this reason the International Electrotechnical Commission (IEC) and the United States have recommended IEEE standards such as IEEE provisions of the current standard harmonic limits shown in Table China Power Grid with the actual level and the standard of other developed countries voltage distortion sine-rate provisions in table Table 1 harmonic current limits (IEEE519-1992 Provisions) Isc / IL H <11 11 35THD <> 0 Table 2 voltage distortion sine-rate limits Supply voltage / kV voltage distortion sine-rate limits / or 3856% 5 4 harmonic comprehensive management At present， China's electric power system harmonics on the management is "pollution first， treatment after" the passive situation，
