【正文】 第四次洽談會(huì)2007年，PCC名古屋會(huì)議 名古屋 會(huì)議項(xiàng)目K 9 K 16，2007。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)。 在這篇文章里，通過分析電流q ，迫使力量達(dá)到了，在打開的過程中，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。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。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程而是一個(gè)S形曲線運(yùn)行的。控制器選擇和使用的是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來控制芯片當(dāng)前特定的保護(hù)。[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。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。 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.
