Ulawulo oluchanekileyo lolwelo (iigesi okanye ulwelo) yenye yeemfuno eziphambili kwicandelo le-automation yemizi-mveliso, izixhobo zonyango, izixhobo zohlalutyo, kwanamakhaya akrelekrele. Nangona iivalvu ze-solenoid zemveli okanye iivalvu zomoya zisetyenziswa kakhulu, zihlala zingaphumeleli kwiimeko ezifuna ukulawulwa kokuhamba okuncinci, ukuphindaphinda okuphezulu kakhulu, ukugcinwa kwesikhundla esipheleleyo, okanye ucwangciso oluntsonkothileyo lokuvula. Ngeli xesha, iimoto ze-micro stepper, ezineenzuzo zazo zokusebenza ezizodwa, ziya ziba "yingqondo ekrelekrele" kunye "nomlawuli oguquguqukayo" weenkqubo zolawulo lweevalvu eziphezulu, ziqhuba utshintsho oluchanekileyo kulawulo lolwelo.
1, Umngeni wolawulo lweevalvu kunye nokulingana okugqibeleleyo kweemoto ezincinci ze-stepper
Iindlela zokulawula iivalvu zemveli, ezinje ngeevalvu ze-solenoid zohlobo lokutshintsha, iivalvu ezilinganayo ezixhomekeke kwizibonakaliso ze-analog okanye iinkqubo zempendulo ezintsonkothileyo, zihlala zijongene nemida elandelayo:
Ukuchaneka okunganelanga:Kunzima ukufezekisa uhlengahlengiso oluchanekileyo lwamazinga okuhamba kwamanzi amancinci kunye nokubekwa kokuvula okuphindaphindwayo kakhulu.
Impendulo kunye nozinzo:Imiqondiso ye-analog isenokuba nokuphazamiseka, kwaye impendulo eguqukayo isenokungabi ntle. Ukugcina indawo ifuna ukusetyenziswa kwamandla okuqhubekayo (ivalvu yesolenoid) okanye uxinzelelo lomthombo womoya (ivalvu yepneumatic).
Ubunzima:Ukufikelela kulawulo oluvaliweyo oluchanekileyo oluphezulu kufuna ii-sensors ezongezelelweyo (ezifana nee-position encoders, ii-flow meter) kunye nee-algorithms zolawulo ezintsonkothileyo, nto leyo enyusa iindleko kunye nomthamo.
Ukusetyenziswa kwamandla kunye nokuveliswa kobushushu:Ivalvu yesolenoid kufuneka ihlale inamandla ukuze igcine indawo yayo, nto leyo ebangela ukusetyenziswa kwamandla kunye nokuveliswa kobushushu.
Ukuvela kwee-motor ze-micro stepper kubonelela ngezisombululo ezikhuphisanayo kakhulu kwezi ngxaki:
Indawo echanekileyo yokuma kwe-loop evulekileyo:Ngaphandle kwesidingo see-sensors zesikhundla esongezelelweyo, ulawulo oluchanekileyo lokuvulwa kwevalvu (i-rotary valve) okanye indawo ye-spool (i-direct acting valve) lunokufezekiswa ngokubala i-pulse, ngesisombululo sokwahlulahlula i-micro step (njenge-1/256 step) ukuya kwi-step angle (njenge-1.8 °), ukufikelela kulawulo lokuhamba komoya oluchanekileyo kakhulu.
