Servo tsav yog ib qho tseem ceeb ntawm kev tswj cov lus tsa suab niaj hnub no, uas yog siv dav hauv kev lag luam robots thiab CNC machining chaw thiab lwm yam khoom siv automation. Tshwj xeeb, servo drives siv los tswj AC cov hlau nplaum ruaj khov synchronous motors tau dhau los ua kev tshawb fawb hotspot hauv tsev thiab txawv teb chaws. Tam sim no, peb-voj tswj algorithm ntawm tam sim no, ceev thiab txoj hauj lwm raws li vector tswj yog feem ntau saws nyob rau hauv tus tsim ntawm AC servo drives. Txawm hais tias qhov ceev kaw-loop tsim tsim nyog lossis tsis ua lub luag haujlwm tseem ceeb hauv tag nrho cov servo tswj qhov system, tshwj xeeb tshaj yog kev tswj xyuas kev ua haujlwm.
Nyob rau hauv qhov ceev kaw-voj ntawm servo drives, qhov tseeb-lub sij hawm ntsuas qhov tseeb ntawm lub cev muaj zog rotor yog qhov tseem ceeb los txhim kho cov yam ntxwv zoo li qub thiab zoo li qub ntawm lub voj nrawm rau kev tswj ceev. Yuav kom nrhiav tau qhov sib npaug ntawm qhov ntsuas qhov tseeb thiab tus nqi ntawm lub cev, cov khoom siv photoelectric incremental feem ntau yog siv los ua qhov ntsuas qhov ntsuas ceev, thiab cov qauv ntsuas kev sib raug zoo sib xws yog M / T ceev ntsuas txoj kev. Txawm hais tias M / T velocimetry txoj kev muaj qee qhov kev ntsuas qhov tseeb thiab qhov ntsuas dav dav, txoj kev no muaj nws qhov tsis xws luag, feem ntau suav nrog: 1) tsawg kawg yog ib qho tiav code disc mem tes yuav tsum tau kuaj pom hauv lub voj voog ntsuas ceev, uas txwv qhov tsawg kawg nkaus. ntsuas ceev; 2) ob lub kaw lus tswj lub sijhawm hloov pauv siv rau kev ntsuas nrawm yog qhov nyuaj rau kev ua kom nruj nruj, thiab qhov ntsuas qhov ntsuas qhov tseeb tsis tuaj yeem lav rau hauv lub sijhawm ntsuas nrog kev hloov pauv loj. Yog li ntawd, nws yog ib qho nyuaj rau kev txhim kho qhov ceev hauv qab no thiab tswj kev ua tau zoo ntawm servo drives hauv cov txheej txheem nrawm nrawm tsim siv txoj kev ntsuas ntsuas no.
