Then according to the essential trial of electric drive system in electric vehicles ( evs ), it is built that the simulation model of induction motor drive system of evs in efficiency optimization control ( eoc ), which suits different motors for simulation and research concerning the running condition of evs. taking nonlinear saturation problem into consideration, simulation study on eoc is proceeded by using an actual motor acting as an example, comparison of eoc with classical u / f control mode is completed at the same time. it is analysed that the variation of losses and their distribution causing by eoc
聯系實際的應用背景，提出了電動車的最大效率控制問題。然後，從電動車電驅動系統的基本特性出發，建立了電動車工況下最大效率控制的感應電機驅動系統模擬模型，通過實例在飽和非線性的條件下進行了最大效率控制的模擬計算。針對感應電機損耗將最大效率控制產生的損耗變化及分佈規律進行了研究，對鐵心損耗的影響進行了分析。 -
Firstly, the current testing localization in the detection of electric bow is analyzed and the new system ' s whole construction developed in this thesis is introduced ; in the 2rd chapter, the embedded 110v dc power supply is analyzed and constructed, and with experiments, some dissonant results such as the fluctuation of output pwm ( pulse width modulation ) pulses, the power noise added to output voltage, and the drop of output voltage have been analyzed and the problems have been broken down one by one ; in chapter 3, stepping motor ' s drive has been systematically dissertated, and combing stepping motor ' s subdivided drive technology, the author develops an intelligent mini - step driving circuit using a main - sub microprocessor structure, which is validated in the hybrid stepper based system ; in the 4th chapter, liquid crystal driving and displaying technology is specified in detail, with one sort of lcd modules ( tlm12864h ), the author develops an feasible circuit for the new testing system, designs a menu mode based program struc ture and brings here some programming codes using franklin c51 programming language ; in chapter 5, the above built system is used in the electric bow ' s practical detection, and the differentiating rate of this system is analyzed
論文首先分析了目前機車受電弓檢修方式存在的局限並概述了本論文研製的受電弓測試系統的體系架構；第二章對系統內置110v直流控制電源進行了分析和設計，結合試驗對輸出pwm振蕩、輸出電源噪聲大、輸出電壓下跌等現象進行了分析並提出解決措施；第三章論述了步進電機的驅動，結合步進電機微步驅動技術研製了基於上下位單片機組的混合式步進電機智能驅動電路，並在試驗中得以驗證；第四章詳述了液晶驅動及顯示技術，利用一款液晶顯示模塊tlm12864h研製出本系統用液晶顯示電路，設計了菜單式的程序結構並以franklinc51編程方式給出部分子程序代碼；第五章則將以上構建的整個系統應用在機車受電弓的實測中，並對測試解析度進行了分析。
