傳動系統(tǒng)和PLC間通信采用FL-NET總線,光纖連接,變頻器與HUB之間,以太網(wǎng)通訊。結(jié)構(gòu)仍以圖2為例。
PLC系統(tǒng)配置了一塊FL612接口模塊和一塊EGD模塊,與各變頻器進行數(shù)據(jù)交換。各變頻器地址均在EGD中配置,傳動與PLC的通信及傳動與傳動之間的通信都是通過EGD來完成數(shù)據(jù)交換的。
FL-NET網(wǎng)絡(luò)以Ethernet為物理層,采用總線拓撲結(jié)構(gòu),是日本采納的一種PLC網(wǎng)絡(luò)標準,其協(xié)議棧高層為UDP/IP+ UDP/IP+獨自循環(huán)通信協(xié)議,保證了通信的實時性。
完成PLC系統(tǒng)與傳動系統(tǒng)間數(shù)據(jù)交換基于EGD(Ethernet Global Data)以太網(wǎng)全局數(shù)據(jù)處理通信,EGD協(xié)議是美國GE自動化公司基于以太網(wǎng)技術(shù)的數(shù)據(jù)交換協(xié)議,它以數(shù)據(jù)報文形式在一個發(fā)送者和多個發(fā)送者之間實現(xiàn)100Mbps數(shù)據(jù)高速傳送,遵循UDP/IP獨自循環(huán)通信協(xié)議。數(shù)據(jù)發(fā)送時間間隔短,安全性強,不易丟失,各站為雙向角色,既是服務(wù)器也是客戶端。
3. 系統(tǒng)控制功能
TMEIC集成控制器完成整個紙機的速度計算與控制、負荷分配計算與控制、電機同步計算與保護等功能。
衛(wèi)生紙機的速度基準以烘缸Yankee為準,Yankee烘缸由兩臺電機驅(qū)動,1#Yankee電機為master,控制方式為速度控制,2#Yankee電機為slave,控制方式為轉(zhuǎn)矩控制,兩臺電機為一個整體,要求速度同步。
抽吸壓輥(SUCTION PRESS)和成形輥(FORMING ROLL)通過網(wǎng)布,形成一個整體,要求速度同步。在抽吸壓輥靠上烘缸之前,抽吸壓輥為master,速度控制模式;當(dāng)抽吸壓輥靠上烘缸以后,抽吸壓輥轉(zhuǎn)換為轉(zhuǎn)矩控制模式,這時候,Yankee1為master,抽吸壓輥和成形輥轉(zhuǎn)變成Yankee1的從動輥,其控制模式轉(zhuǎn)成轉(zhuǎn)矩控制。
SP_R:速度給定 T_R:轉(zhuǎn)矩給定 IQ_R:轉(zhuǎn)矩分量給定 IQ_F:IQ電流反饋
SP_F:速度反饋 FL_R:磁通給定 ID_R:磁場分量給定 ID_F:ID電流反饋
TENS_R:轉(zhuǎn)矩給定
圖3為傳動矢量控制圖。從圖中可以看出,逆變器的傳動矢量控制由速度給定環(huán)節(jié)、速度調(diào)節(jié)器、D/Q軸電流調(diào)節(jié)器、磁通調(diào)節(jié)器、電壓調(diào)節(jié)器、PWM控制器等組成。
在正常速度控制模式下,速度給定值(SP_REF1)通過FL-Net總線從PLC傳送到矢量控制系統(tǒng)給定積分單元,該單元將階躍信號(SP_REF)轉(zhuǎn)換為按一定變化率隨時間而增減的輸出信號(SP_R),作為速度給定值,使調(diào)速系統(tǒng)的速度帶有一定的加速度,并對加速度和減速度分別作出限幅再送到速度調(diào)節(jié)器。
當(dāng)速度控制模式轉(zhuǎn)換成轉(zhuǎn)矩控制模式時,從動輥的速度環(huán)是開環(huán)的,這樣,電流環(huán)內(nèi)環(huán)給定“TENS_R2”直接來自于主動輥的實際轉(zhuǎn)矩電流“T_R”。負荷分配系數(shù)從DCS給定,調(diào)整范圍0.5-1.5。
