外文翻譯--一個永磁直線同步電動機驅(qū)動的電梯門機的設計與研究(存儲版)
【正文】 into m sampling points, and then set corresponding to each sampling time and speed, the sampling rate corresponds to the value of time and stored in the DSP control chip as a standard reference volume control. [4][5] When the door running, through the actual rate of speed circuit is established by the reference value and pared to the value derived from the signal input to the DSP in order to achieve the running speed of door control.IV. SYSTEM SOFTWARE DESIGNDoor control program is an important part of system control, this control program is modular in design,each functional module and other modules when the shared variable shield, it can run independently, it is a good system for debugging and modification. This control procedure includes the main program and several subroutines。雖然直線電機速度的性能是容易控制，但存在評論：可靠性差，且容易產(chǎn)生電磁干擾和火花，還需要直流電源，因此難以維持。[2] [3]采用光電編碼器檢測門的運行的位置和速度。請鍵入文字或網(wǎng)站地址，或者上傳文檔。[6]自學設計門寬度的自學設計的測量過程自學設計了四種狀態(tài)，低速的關(guān)閉狀態(tài)，門正常的關(guān)閉狀態(tài)，低速開啟狀態(tài)，門正常的開啟狀態(tài)。在關(guān)閉過程中，被迫關(guān)閉力是動力，電力負荷的增加，電流也顯著增加。IEEE磁交易，44（6）：1526年至1529年，2008年。[8]錢偉，Thomas A Nondhal. 表面貼裝的永磁同步電機的相互轉(zhuǎn)矩脈動抑制。 IEEE國際電機和驅(qū)動器會議，（3）：1832年至1836年，2003年[7] Zhu .

INTRODUCTIONThe traditional elevator door, warehouse door and civil came dooropening always drove by motor, because crane is a straightline motion electromechanical integration device of frequent reciprocating,not only its operation and good safety requirements, but the smooth operation and low the door is straightline motion with reciprocating movement,the designation of a mechanical device,which transition the rotary motion of the motor to straightline motion needed to realize the door open/close,is necessary.[1] At present elevator door market in domestic,drive motor mostly adopt AC asynchronous motor or linear motor, due to the high speed,position and difficult control of the AC asynchronous motor,it must have slow institutions contains belt or gear transmission etc,which make its structure plex,efficiency lowly,noisy and the performance of speed poorly. Though the performance of speed of linear motor is easy,but for the existence of mentator,the reliability is poor,and easy to produce electromagnetic interference and spark,also need DC electrical source,difficulty to using a PMLSM as drive motor,can save the transmission mechanism between motor and the gate,direct driving gear for linear motion,improve the reliability
