【正文】 外文翻譯Linear Matrix InequalityBased Fuzzy Control for Interior Permanent Magnet Synchronous Motor with integral sliding mode controlFaGuang Wang, Seung Kyu Park, Ho Kyun AhnDepartment of Electrical Engineering, Changwon National University, KoreaAbstractRecently, interior permanent magnet synchronous motor (IPMSM) is widely used in various applications, such as electric vehicles and pressors. It has a high requirement in wide load variations, high speed condition, stability, providing a fast response and most important thing is that it can be applied easily and efficiently. However, the control of IPMSM is more difficult than surface permanent magnet synchronous motor (SPMSM) because its nonlinearity due to the nonzero daxis current which can be zero in SPSM but not IPMSM. In this paper, the IPMSM is controlled very efficient algorithm by using the bination of linear control and fuzzy control with linear models depending on certain operating points. The H∞ linear matrix inequality (LMI) based integral sliding mode control is also used to ensure the robustness. The membership functions of this paper are easy to be determined and implemented easily. Index TermsFuzzy control, H∞ control, integral sliding mode control, interior permanent magnet synchronous motor (IPMSM), linear matrix inequality.I. INTRODUCTIONFrom 1980s’, with the development of semiconductor, IPMSM supplied by converter source has been widely studied [1] [2]. The development of microputer made the vector control system of IPMSM well controlled by single chip. IPMSM possesses special features for adjustablespeed drives which distinguish it from otherclasses of ac machines, especially surface permanent magnet synchronous motor. The main criteria of high performance drives are fast and accurate speed response, quick recovery of speed from any disturbances and insensitivity to parameter variations [3]. In order to achieve high performances, the vector control of IPMSM drive is employed [4][6]. Control techniques bee plicated due to the nonlinearities of the developed torque for nonzero value of daxis current. Many researchers have focused their attention on forcing the daxis current equals to zero in the vector control of IPMSM drive, which essentially makes the motor model linear [4],[7]. However, in realtime the electromagnetic torque is nonlinear in nature. In order to incorporate the nonlinearity in a practical IPMSM drive, a control technique known as maximum torque per ampere (MTPA) is devised which provides maximum torque with minimum stator current [3]. This MTPA strategy is very important from the limitation of IPMSM and inverter rating points of view, which optimizes the drive efficiency. The problem associated MTPA control technique is that its implementation in real time bees plicated because there exists a plex relationship between daxis and qaxis currents. Thus, one of the main objectives of this paper is to make a new efficient control method for IPMSM and its calculation easy and efficient. The LMI fuzzy H∞ control has been applied and solved the nonlinearity of the IPMSM model to a set of linear model. To increase the robustness for disturbances, an ISMC technique is added to the H∞ controller. By ISMC, the proposed controller gives performances of the H∞ control system without disturbances which satisfy the matching condition. It has a good patible with linear controllers. TS fuzzy control [8] is based on the mathematical model which is the bination of local linear models depending on the operating points. Linear controllers are。我會(huì)更加努力，爭(zhēng)取更進(jìn)一步。 參考文獻(xiàn)[1] 《電動(dòng)機(jī)原理與實(shí)用技術(shù)》 王益全編著 科學(xué)出版社2005[2] 《電機(jī)控制》 徐大中 賀益康編著 浙江大學(xué)出版社2002[3] 《交流電機(jī)動(dòng)態(tài)分析》 湯蘊(yùn) 張奕黃 范瑜編著 機(jī)械工業(yè)出版社 2004[4] 《交流電機(jī)變頻調(diào)速及其應(yīng)用》 張承慧 李珂編著 機(jī)械工業(yè)出版社 2008[5] 《AUTOCAD2004 入門與提高》 張躍峰等編 清華大學(xué)出版社[6] 《電機(jī)設(shè)計(jì)》 陳世坤編 機(jī)械工業(yè)出版社[7] 《電機(jī)學(xué)》 李發(fā)海 朱東起編著 科學(xué)出版社 2001[8] 《電路》邱關(guān)源編著 華中科技大學(xué)大學(xué)出版社 2006[9] 電機(jī)工程手冊(cè). 北京：機(jī)械工業(yè)出版社，1996.[10] 上海電器科學(xué)研究所《中小型電機(jī)手冊(cè)》：機(jī)械工業(yè)出版社，1994[11] 《交流電機(jī)及其系統(tǒng)的分析》 高景德 李發(fā)海編著 清華大學(xué)出版社 2005[12] 《現(xiàn)代新型無刷勵(lì)磁同步電動(dòng)機(jī)的設(shè)計(jì)及應(yīng)用》 李幼倩編著 機(jī)械工業(yè)出版社2009[13] 《電動(dòng)機(jī)控制》 黃立培主編 清華大學(xué)出版社 2003[14] 《電機(jī)學(xué)》 戴文進(jìn) 徐龍權(quán)編著 清華大學(xué)出版社 2008致謝在這幾個(gè)月的學(xué)習(xí)當(dāng)中，我感受很多，首先要謝謝黃老師和師哥師姐們的細(xì)心幫助，是他們不厭其煩的關(guān)懷才使我能夠比較順利的完成了這次設(shè)計(jì)。我們可以好好的利用這次機(jī)會(huì)來檢驗(yàn)鍛煉一下我們科學(xué)研究的能力，在遇到問題時(shí)我們要養(yǎng)成良好的習(xí)慣，學(xué)會(huì)運(yùn)用身邊的工具，如書本，老師，同學(xué)，資料庫等一切可以利用的資源來為我們服務(wù)，來解決問題。在對(duì)三個(gè)方案的設(shè)計(jì)中，我們可以清楚的學(xué)習(xí)到什么參數(shù)會(huì)影響到同步電動(dòng)機(jī)的哪一種性能，通過改變這些的參數(shù)便可以對(duì)電機(jī)的性能作出調(diào)整，從而設(shè)計(jì)出自己覺得符合設(shè)計(jì)目的的同步電動(dòng)機(jī)。在理清了思路后便開始著手設(shè)計(jì)計(jì)算了，在計(jì)算的時(shí)候?qū)ν诫妱?dòng)機(jī)的各種參數(shù)的認(rèn)識(shí)理解還是有所欠缺，這就導(dǎo)致不能很好的把握住問題的重點(diǎn)所在，不如在定子槽形的確定過程中，由于要符合槽滿率的要求，在這部份的設(shè)計(jì)中便反反復(fù)復(fù)的修改槽型，當(dāng)時(shí)覺得很費(fèi)事用沒有什么用處但現(xiàn)在看來這部分是最有意義的，因?yàn)椴粌H鍛煉了我們解決問題的能力，還培養(yǎng)了我們的耐心。圖 定子沖片圖 轉(zhuǎn)子沖片圖 單相繞組圖三相繞組圖第八章 設(shè)計(jì)總結(jié)在這次的變頻調(diào)速同步電動(dòng)機(jī)控制系統(tǒng)及其電磁計(jì)算設(shè)計(jì)的過程中，我學(xué)到了很多的內(nèi)容，這些東西是單純從課本上學(xué)不到的，感受很多。了解關(guān)鍵用戶界面組件；創(chuàng)建新圖形并打開已有圖形；平移和縮放圖形，創(chuàng)建和恢復(fù)命名視圖；通過確定點(diǎn)和線創(chuàng)建二維幾何圖形；從基本幾何圖形創(chuàng)建對(duì)象，諸如圓、橢圓、矩形、多線段、圓弧、樣條曲線和構(gòu)造線；理解圖層并使用圖層特性管理器來創(chuàng)建圖層和修改它們的特性；使用不同的方法來選擇要編輯的對(duì)象；通過使用復(fù)制、修剪、延伸、偏移、倒角、圓角、陣列、多段線編輯、鏡像和拉伸來編輯和修改對(duì)象以創(chuàng)建幾何圖形；使用夾點(diǎn)編輯對(duì)象；使用文本樣式創(chuàng)建文本，并利用填充樣式和漸變填充來增強(qiáng)圖形效果；通過使用標(biāo)注樣式來對(duì)圖形進(jìn)行尺寸標(biāo)注；使用查詢命令計(jì)算面積、周長和質(zhì)量特性，并顯示對(duì)象的數(shù)據(jù)庫信息；通過使用快和外部塊，共享和再利用圖形。在這里我將使用AUTO CAD 2007繪制定子沖片圖，轉(zhuǎn)子沖片圖，電樞繞組圖。綜上所述，在同步電動(dòng)機(jī)的設(shè)計(jì)過程中要綜合整體方面的要求，照顧到全方面的利益，最終確定符合要求的方案。在方案三的設(shè)計(jì)過程中，降低了每槽導(dǎo)體數(shù)，這就要求改變電樞繞組的線規(guī)來滿足槽滿率的范圍，線規(guī)的改變使得電樞繞組的電密比要求小了一點(diǎn)。但是總體的重量還是減小到了預(yù)期的目的。在方案二中，由于氣隙磁密的增大導(dǎo)致了電樞鐵心長度的減小，還有電樞銅重、電樞齒部重、電樞軛部中、硅鋼片重、磁極鋼片重都減小了。由對(duì)比可以看出相對(duì)于第一個(gè)方案，方案二在氣隙磁密的選擇上有所改變，氣隙磁密增加了從而達(dá)到了節(jié)省材料的目的，但是電動(dòng)機(jī)的效率有所下降。槽滿率太高了在嵌線時(shí)極易引起絕緣損傷，將造成電機(jī)報(bào)廢等比較嚴(yán)重的后果。較高的槽滿率值不僅可以縮小槽面積，鐵心尺也可應(yīng)縮小，提高材料的利用率；而且有利于槽內(nèi)導(dǎo)線的散熱。 槽滿率對(duì)電機(jī)的影響當(dāng)槽滿率變小時(shí)，電樞繞組電密會(huì)變大，相應(yīng)的電樞發(fā)熱參數(shù)升高，因而不利槽內(nèi)導(dǎo)線的散熱。但因?yàn)榧庸さ膯栴}，氣隙不可能做的很小。電機(jī)的磁阻主要集中在電機(jī)的氣隙上，電機(jī)的氣隙主要影響電機(jī)的主磁通和電磁轉(zhuǎn)矩。 電機(jī)氣隙大小對(duì)電機(jī)的設(shè)計(jì)的影響 氣隙控制是生產(chǎn)電機(jī)的一個(gè)重要參數(shù)，電機(jī)生產(chǎn)廠會(huì)控制很嚴(yán)格。此外，在同步電機(jī)里，瞬變電抗也與漏抗的大小密切相關(guān)，而瞬變電抗對(duì)電機(jī)的動(dòng)態(tài)特性有很大的影響。一方面漏抗不能過小，否則同步電動(dòng)機(jī)短路時(shí)或感應(yīng)電動(dòng)機(jī)啟動(dòng)時(shí)將產(chǎn)生不能允許的電流。感應(yīng)電機(jī)轉(zhuǎn)子電阻的大小對(duì)其轉(zhuǎn)距特性影響特別突出。例如在設(shè)計(jì)繞組時(shí)，如果選取較高的電流密度，則所用的導(dǎo)體截面就較小，用銅量就較少而電阻就較大。其中電阻包括直流電阻和交流電阻，而電抗包括主電抗和漏電抗，對(duì)于同步電機(jī)，主電抗叫做電樞反應(yīng)電抗，而對(duì)于異步機(jī)來說則叫做勵(lì)磁電抗，漏電抗則包括槽漏抗、端部漏抗、齒頂漏抗和諧波漏抗。然后分別繪制部件的分裝配圖和零件圖，并對(duì)總裝配草圖進(jìn)行必要的修改。結(jié)構(gòu)設(shè)計(jì)：結(jié)構(gòu)設(shè)計(jì)的任務(wù)是確定電機(jī)的機(jī)械結(jié)構(gòu)、零部件尺寸、加工要求與材料的規(guī)格及性能要求，包括必要的機(jī)械計(jì)算及通風(fēng)和溫升計(jì)算。因?yàn)?，則第四章 電機(jī)設(shè)
