Henan Polytechnic UniversityJiao Zuo, ChinaEmail:Renning66Abstract:Most of the existing elevator door driven by rotary motors, this paper used to design the permanent magnet linear synchronous motor as the Drive Fixed Motor,the door can eliminate the need of drive mechanism between the motor and the door, direct drive door in a straight line,improve reliability and security of the door machine. Through experimental analysis, the design uses DSP and Intelligent Power Module (IPM) bination of control system for elevator door operation by setting curve and stable operation.Keywords: Permanent magnet linear synchronous motor。mainly include controller,SPWM,signal generator,rectifier circuit,intelligent power module IPM and sensors, etc. The controller selects and uses the TI Company’s TMS320LF2407, 2407 has builtin module and pulse coding capture circuit, which can produce PWM power module IPM uses Fuji Company’s 6MBP15RH060,to simplify the power circuit design by the builtin drive system’s designation is mainly revolves control chip 2407 and intelligent power module IPM, using hall current sensor monitoring electric current on realtime, the current signal sent to DSP control chip to current peculiar protection.[2][3] Adopting photoelectric encoder detecting the door’s operating position and speed.Figure 2 control system handware structureC. System controller chart The control system use feedback control on three close loops: the position P,velocity V,and current I, diagram of system controller block as shown in Figure 3. The control process is,first of all, pare location P measured by optical encoder and position mand P*,then find the speed mand value V* by the position controller,the signal by pared V with V* after the speed controller find the current vector mand I。關(guān)鍵詞:永磁直線同步電動(dòng)機(jī)。[1] 目前在國(guó)內(nèi)的電梯門市場(chǎng),驅(qū)動(dòng)電機(jī)大多采用交流異步電機(jī)或直線電機(jī),由于交流異步電動(dòng)機(jī)要求高的速度,位置精度,并且難以控制,因此它必須有包含皮帶或齒輪傳動(dòng)等緩慢的機(jī)構(gòu),但這種機(jī)構(gòu)使得其結(jié)構(gòu)復(fù)雜,效率低,噪音和速度性能不佳。系統(tǒng)的控制電路采用的是TMS320LF240X TI公司LF2407系列作為控制芯片,與智能功率模塊IPM結(jié)合起來(lái),根據(jù)曲線設(shè)置來(lái)實(shí)現(xiàn)門的穩(wěn)定運(yùn)行??刂破鬟x擇和使用的是TI公司的TMS320LF2407,2407內(nèi)置的模塊和脈沖編碼采集電路,簡(jiǎn)化內(nèi)置驅(qū)動(dòng)電路的電源電路設(shè)計(jì),控制系統(tǒng)主要是圍繞控制芯片2407和智能功率模塊IPM制定的,使用霍爾電流傳感器監(jiān)測(cè)實(shí)時(shí)電流,將電流信號(hào)發(fā)送到DSP來(lái)控制芯片當(dāng)前特定的保護(hù)。由電流傳感器檢測(cè)電機(jī)電流Ia和Ib,然后通過(guò)加法器將Ia和Ib相加獲得Ic,再經(jīng)過(guò)坐標(biāo)轉(zhuǎn)換成一個(gè)q軸和d軸電機(jī)電流的電流,以實(shí)現(xiàn)閉環(huán)負(fù)反饋控制, 通過(guò)電編碼器和速度指令V *比較測(cè)量的速度,從而實(shí)現(xiàn)電機(jī)速度的負(fù)反饋。圖中顯示了門的速度運(yùn)行不是以一個(gè)線性的加速或減速過(guò)程而是一個(gè)S形曲線運(yùn)行的。四、系統(tǒng)軟件設(shè)計(jì)門控制程序是一個(gè)系統(tǒng)控制的重要組成部分,這種控制方案是采用模塊化設(shè)計(jì),各功能模塊和其他模塊共享變量盾,可以獨(dú)立運(yùn)行,這是一個(gè)良好的可以用于調(diào)試和修改的系統(tǒng)。初始化完成后,進(jìn)入主循環(huán),系統(tǒng)在設(shè)置參數(shù)的控制下運(yùn)行。本文通過(guò)d軸和q軸電流的獲取實(shí)現(xiàn)了門機(jī)的控制。 在這篇文章里,通過(guò)分析電流q ,迫使力量達(dá)到了,在打開(kāi)的過(guò)程中,被迫關(guān)閉的能力是負(fù)載力,當(dāng)門在第一速度之后減慢時(shí),電流會(huì)隨之增加,然后又馬上下降。參考文獻(xiàn)[1]王克,黎明石,耀華力和何金威。采用Halbach陣列[J]對(duì)同步永磁平面電機(jī)進(jìn)行最大限度地減少普通推力的設(shè)計(jì)。[4] Pai, R.
