1.Ukwakheka okujwayelekile kwe-stepper motor open-loop servo system
Izikhathi zokuvula nokuvala zemoto yokunyathela kanye nokulandelana kwamandla kwesigaba ngasinye kunquma ukuphuma kwe-angular kanye nesiqondiso sokunyakaza.I-control pulse distribution frequency ingakwazi ukufeza ukulawulwa kwesivinini semoto enyathelayo.Ngakho-ke, uhlelo lokulawula i-stepper motor ngokuvamile lusebenzisa ukulawulwa kwe-open-loop.
2.Ukulawulwa kwehardware ye-stepper motor
I-steping motor iphendulela i-engeli yesinyathelo ehambisanayo ngaphansi kwesenzo se-pulse, inqobo nje uma inani elithile lama-pulses lilawulwa, i-engeli ehambisanayo lapho i-stepping motor ijika ingalawulwa ngokunembile.Kodwa-ke, ama-windings we-steping motor kufanele anikezwe amandla ngendlela ethile ukuze asebenze kahle.Le nqubo yokwenza i-motor ivuleke futhi ivale ngokuhambisana nokulawula ama-pulses okufakwayo ibizwa ngokuthi ukusabalalisa kwe-ring pulse.
Kunezindlela ezimbili zokuzuza isabelo esiyindilinga.Enye iwukusabalalisa isofthiwe yekhompyutha.Ukubheka ithebula noma indlela yokubala isetshenziselwa ukwenza amaphinikhodi amathathu okukhiphayo ekhompuyutha akhiphe ngokulandelana isignali yokusabalalisa eyindilinga ehlangabezana nezidingo zejubane nendawo.Le ndlela ingasebenzisa ngokugcwele izinsiza zesofthiwe yekhompiyutha ukunciphisa izindleko ze-hardware, ikakhulukazi ukusatshalaliswa kwe-pulse yama-motors ezigaba eziningi kubonisa izinzuzo zayo.Kodwa-ke, ngenxa yokuthi isoftware esebenzayo izothatha isikhathi sokusebenza kwekhompiyutha, isikhathi esiphelele sokusebenza kwe-interpolation sizokhula, okuzothinta ijubane lokugijima le-stepper motor.
Okunye ukusabalalisa indandatho yehadiwe, okusebenzisa amasekhethi edijithali ukwakha noma amadivaysi akhethekile okusabalalisa indandatho ukucubungula amasiginali we-pulse eqhubekayo kanye nama-pulses ring okukhiphayo ngemva kokucubungula isekethe.Abasabalalisi bendandatho abakhiwe ngamasekhethi edijithali ngokuvamile bahlanganisa izingxenye ezihlukene (ezifana nama-flip-flops, amasango anengqondo, njll.), ezibonakala ngosayizi omkhulu, izindleko eziphezulu, kanye nokuthembeka okubi.
