【正文】 ate value is called delay （通常是50%）的時間叫做延遲時間。它衡量主導(dǎo)極點的阻尼。像阻尼比一樣，它可能被應(yīng)用到二階或高階系統(tǒng)來確定主導(dǎo)極點。第四篇：電氣工程及其自動化專業(yè)英語介紹Electrical Engineering and AutomationElectrical Engineering and Automation was created at forty years a new subject, it is relating to many walks of life, small to a switch designed to study aerospace aircraft, has its Engineering and Automation of electrical information professional is an emerging field of science, but because of people39。familiar with a variety of main electrical equipment and related standards, rich experience in project in 3D design software and Office office automation software, serious and responsible work, cooperation consciousness and organizational skills, able to work under pressure.。s degree Height: 180cmContact telephone number: ***EMAIL: lwb564226349Contact address: Zhao Zhai Village Zi Ling town Qinyang city Henan province Zip code: 454592Home address: Zhao Zhai Village Zi Ling town Qinyang city Henan provinceZip code: 454592Occupation skilll Foreign language ability： CET4 CET6 l Computer skills： NCRE2l Familiar with puter operation, skilled use of office and Internet series of office software applicationl Master the C language, assembly language, MATLAB, CAD and so on, has the strong ability of programming and program experience Henan University of Technology Qinyang First Middle High SchoolProfessional coursesMajor courses： Circuit theory, modern control theory and sampling system, power electronics technology, power supply and distribution system, the principle of automatic control，Motor learning, analog electronic technology, digital electronic technology, distributed control system, PLC principle and application, Single chip microputer principle and interface technology,Power system analysis courses: microeconomics, macroeconomics, introduction to the world economy, international financial, accounting, MultiNational Corporation and direct investment, international trade, business English practice/Internship experience2015 July internship in Shanghai Hualian Supermarket Design in 2015 August involved in Shanghai electric scientific research, test switch(mainly used for high pressure two times side)Self evaluation Electrical solid theoretical foundation, abundant project experience。誤差系數(shù)用來把單位反饋系統(tǒng)的增益及時間常數(shù)和系統(tǒng)誤差聯(lián)系在一起。阻尼比是一個重要的用來確定系統(tǒng)的瞬態(tài)性能和穩(wěn)定性的參數(shù)。Bandwidth帶寬The bandwidth is defined as the frequency at which the output magnitude is pared to the output magnitude at low(or zero)frequency when the system is subjected to sinusoidal ，當(dāng)系統(tǒng)在正弦形式輸入作用下，在該頻率上輸出幅值和低頻（或零頻） Ratio阻尼比This is a ratio of the system damping to the critical damping for a secondorder system。有時用一個等效值來代替上升時間，及響應(yīng)達到穩(wěn)態(tài)值的50%時，輸出響應(yīng)上升斜率的倒數(shù)。這些極點就是那些位于離虛周最近的極點。這是系統(tǒng)在不穩(wěn)定部分內(nèi)輸入和輸出之間最大的誤差的象征。Control system specifications can directly related to system response as shown in the Fig type of information is germane to secondorder systems of higherorder systems which have a pair of characteristic zeroes that are plex and dominate the transient example ,a system with characteristic zeroes at5,10++j2 is a fifthorder system but the dominant zeroes + monly used terms to describe system specification are peakovershoot ,rise time ,delay time ,setting time ,bandwidth ,damping ratio and undamped natural 。The performance that of a control system can be considered in three first part pertains to the specification as they directly relate to system second has to do with aperformance index that is a functionof the erroror last part is concerned with system error caused by parameter 。第一篇：電氣工程與自動化專業(yè)英語第一單元1． electrostati靜電的 2． charge 電荷 3． positive 正的 4． negative 負(fù)的 5． electron電子 6． proton 質(zhì)子7． gravitational引力的 8． precipitator 電濾器 9．power plant 發(fā)電廠 10． current電流 11． conductor導(dǎo)體 12．insulator 絕緣體13．semiconductor半導(dǎo)體 14．valence shell 價電子層 15．Silicon硅 16．germanium 鍺 17．selenium硒 18．voltage 電壓 19．resistance 電阻 20．circuit電路21．electromotive force(EMF)電動勢22．repel 排斥23．multimeter 萬用表 24．milliammeter 毫安表 25．a(chǎn)mmeter安培表 26．ohmmeter歐姆表 27．voltmeter 電壓表 28．polarity 極性 29．parallel 并聯(lián) 30．series 串聯(lián) 31．filament燈絲 32．resistor 電阻器 33．hot wire火線 34．neutral wire中線 35．phase 相位36．electrical power電源 37．cylinder圓柱38．electroma
