【正文】 ule (IPM) bination of control system for elevator door operation by setting curve and stable operation. Keywords: Permanent mag linear synchronous motor。 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 chart III. DOOR OPERATION CURVE DESIGN Door 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 curve This 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 DESIGN Door 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。電梯門機(jī)制 。雖然直線電機(jī)速度的性能是容易控制,但存在評(píng)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。 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(dòng)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。 [2] [3]采用光電編碼器檢測(cè)門的 運(yùn)行的 位置和速度。實(shí)驗(yàn)結(jié)果表明,該控制器是容易實(shí)現(xiàn)電梯門的控制和調(diào)試。 Figure 4 Machine running curve 這部分第一次進(jìn)行曲線離散,分為米的采樣點(diǎn),然后設(shè)置相應(yīng)的每個(gè)采樣時(shí)間和速度,將在相應(yīng)時(shí)間值里的采樣率存儲(chǔ)在一個(gè)標(biāo)準(zhǔn)的參考音量控制的 DSP 控制芯片上。 主程序包括系統(tǒng)初始化和主循環(huán)體組成。工藝流程圖顯示在圖 5。當(dāng)門關(guān)閉或完全 打開時(shí) , iq是大約為 0, iq 是一個(gè)固定值。 Figure 6 displacements and the current curve Figure 7 qaxis coercion to force and non 六、 結(jié)論 通過實(shí)驗(yàn)的分析,使用永磁同步直線電機(jī)作為驅(qū)動(dòng)電機(jī),實(shí)現(xiàn)了電梯門在默認(rèn)情況下的運(yùn)行曲線,而且門系統(tǒng)可靠,低噪音。 IEEE工業(yè)電子與應(yīng)用第三會(huì)議。 [3]Yamaguchi,T.
