1.PLC 控制技術前言：

    全自動真空包裝機可以根據控制中心可以隨意設定包裝袋所填充的物料大小智能稱重，基本上誤差在±2g區間，其實這個過程需要依靠可編程邏輯控制器也就是PLC作為一種通用控制裝置，PLC技術已經廣泛應用于很多個領域，這其中就包括曉松智能所生產的真空包裝機。真空包裝機是一種全自(zi)動的包(bao)裝(zhuang)生產裝(zhuang)置，其可以同時進行多工位生產將稱量好的物(wu)料投放到(dao)包(bao)裝(zhuang)袋(dai)中，大大提高包(bao)裝(zhuang)速度。

2.PLC 控制技術特點：

    全自動真空(kong)包(bao)(bao)(bao)裝機根據系統(tong)(tong)設定(ding)質量(liang)，實(shi)(shi)時對(dui)物料進(jin)行稱(cheng)量(liang)與(yu)修正，實(shi)(shi)現(xian)包(bao)(bao)(bao)裝機對(dui)物料的準確控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。為(wei)了(le)(le)進(jin)一步提(ti)高(gao)包(bao)(bao)(bao)裝機稱(cheng)量(liang)系統(tong)(tong)的控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)精度，采用以包(bao)(bao)(bao)裝物料為(wei)研究對(dui)象(xiang)，將(jiang)模(mo)糊(hu)(hu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)與(yu) PID 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)相(xiang)結合(he)(he)，提(ti)出(chu)模(mo)糊(hu)(hu) PID 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。將(jiang) PLC 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)技術與(yu)模(mo)糊(hu)(hu) PID 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)融合(he)(he)，利用 PLC控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)技術實(shi)(shi)現(xian)對(dui)包(bao)(bao)(bao)裝機稱(cheng)量(liang)系統(tong)(tong)的模(mo)糊(hu)(hu)PID控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。這(zhe)樣的控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)方式既保留了(le)(le) PLC 控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系統(tong)(tong)可靠性高(gao)、適應性強的特點(dian)又(you)加(jia)入了(le)(le)模(mo)糊(hu)(hu) PID 對(dui)非線性系統(tong)(tong)具有(you)良好控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)效果(guo)的特點(dian)，大(da)大(da)提(ti)高(gao)了(le)(le)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系統(tong)(tong)的智能化(hua)，是(shi)當今控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系統(tong)(tong)的發(fa)展趨勢。

3.PLC 控制技術特點小結：

    包裝行業普(pu)遍采用電磁振(zhen)動(dong)給料(liao)(liao)(liao)裝置實(shi)現物料(liao)(liao)(liao)的補給，但由于物料(liao)(liao)(liao)與(yu)給料(liao)(liao)(liao)機(ji)(ji)之間(jian)存(cun)在非線性與(yu)時(shi)變性的特(te)點，這使(shi)得包裝稱(cheng)量精度存(cun)在一定的誤差。很多傳統的包裝機(ji)(ji)稱(cheng)量系(xi)統的精度在±3g范(fan)圍內。
