這樣，用PLC實(shí)現(xiàn)模擬量控制是*可能的。控制的單位值可小到212分之一的測量程值，多數(shù)也是足夠的。
PLC進(jìn)行模擬量控制，還有A/D、D/A組合在一起的單元，并可用PID或模糊控制算法實(shí)現(xiàn)控制，可得到很高的控制質(zhì)量。
用PLC進(jìn)行模擬量控制的好處是，在進(jìn)行模擬量控制的同時，開關(guān)量也可控制。這個優(yōu)點(diǎn)是別的控制器所不具備的，或控制的實(shí)現(xiàn)不如PLC方便。
當(dāng)然，若純?yōu)槟M量的系統(tǒng)，用PLC可能在性能價格比上不如用調(diào)節(jié)器。這也是應(yīng)當(dāng)看到的。
3.3用于運(yùn)動控制
實(shí)際的物理量，除了開關(guān)量、模擬量，還有運(yùn)動控制。如機(jī)床部件的位移，常以數(shù)字量表示。
