671,2001。 IEEE國際電機(jī)和驅(qū)動器會議,(3):1832年至1836年,2003年[7] Zhu . Halbach永磁機(jī)和應(yīng)用的最新發(fā)展。2010年國際電子自動化控制會議(ICEEAC 2010)。[8]錢偉,Thomas A Nondhal. 表面貼裝的永磁同步電機(jī)的相互轉(zhuǎn)矩脈動抑制。 IEEE磁交易 23(6):39083915,1987。IEEE磁交易,44(6):1526年至1529年,2008年?;陔妷菏噶砍〉耐屏驼M屏Φ慕怦畹目刂七x擇[C]。在關(guān)閉過程中,被迫關(guān)閉力是動力,電力負(fù)荷的增加,電流也顯著增加。[7] [8]單門的最大位移45mm,門的位移和電流的實驗曲線如圖6所示。[6]自學(xué)設(shè)計門寬度的自學(xué)設(shè)計的測量過程自學(xué)設(shè)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)。這個控制程序包括主程序和若干子程序,其主要功能是通過設(shè)置特征,如運行速度曲線,來完成門和修改后的門操作的控制運行參數(shù)的控制。請鍵入文字或網(wǎng)站地址,或者上傳文檔。實驗結(jié)果表明,該控制器是容易實現(xiàn)電梯門的控制和調(diào)試。[2] [3]采用光電編碼器檢測門的運行的位置和速度。Figure 1 Mechanical structure diagram of elevator door二、電路控制系統(tǒng)表1的永磁直線同步電動機(jī)的具體參數(shù)本文使用帶有磁性的有限元軟件來進(jìn)行PMLSM建模。雖然直線電機(jī)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。電梯門機(jī)制。 detected motor current Ia and Ib by current sensor,then through the adder add Ia and Ib obtain Ic,then after coordinate transformation into a qaxis and d axis current of the motor current to achieve closedloop negative feedback speed V measured by the optical encoder and speed mand V* to realize the negative feedback of motor experimental results show that the controller is easy to implement on the elevator door control and debugging.Figure 3 system controller chartIII. DOOR OPERATION CURVE DESIGNDoor operating curves shown in Figure 4, The figure for the single horizontal stroke fan elevator door, the vertical axis for the single fan speed elevator door. Above the xcoordinate for closes the running status curve, underneath for opens the running status curve. The figure shows the Door speed run is not run as a linear process of acceleration or deceleration, but to run as an Sshaped curve. Figure 4 Machine running curveThis section first run curve discrete, divided 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。畢業(yè)設(shè)計(論文)——外文翻譯(原文)Design and Research of a PMLSMDriven Elevator Door MachineWang Xudong, Ren Ningning, Xu XiaozhuoSchool of Electrical Engineering and Automation
