Kodi akupanga Cake Cutter amakwanitsa bwanji kuyika zinthu mwachangu komanso moyenera? Yankho ndi: servo control. Ndiye, servo control ndi chiyani?

 

Servo control, that is, human activities that control the generated motion and the motion of objects to meet a certain purpose. The so-called servo control refers to the effective control of the changes in the position, speed and acceleration of the object movement. This kind of control has been popularized in various fields. Servo control system refers to a feedback control system used to accurately follow or reproduce a process.

 

1. Dongosolo la servo litha kugawidwa m'magulu otsatirawa:

  1. Lamulo gawo: chipangizo chotulutsa cha chizindikiro cholamula
  2. Gawo loyendetsa: chipangizo chomwe chimalandira kutulutsa kwa gawo lamalamulo ndikuyendetsa zochita za actuator (monga mota)
  3. Feedback gawo: chipangizo chozindikirira momwe akugwirira ntchito kapena momwe akulemedwera
  4. Actuator: Landirani chizindikiritso cha gawo loyendetsa kuti mupange torque, malo ndi mayiko ena

 

2. Mapangidwe amkati a servo:

 

3. Njira yolamulira

Nthawi zambiri, servo ili ndi njira zitatu zowongolera: mawonekedwe owongolera liwiro, mawonekedwe owongolera ma torque, ndi mawonekedwe owongolera.

 

4. Kuyerekeza njira zitatu zowongolera:

  1. Ngati palibe chofunikira pa liwiro ndi malo agalimoto, bola ngati torque yokhazikika ikutuluka, mawonekedwe a torque amagwiritsidwa ntchito.
  2. Ngati pali kufunikira kolondola kwa malo ndi liwiro, koma osakhudzidwa kwambiri ndi torque yeniyeni, sikoyenera kugwiritsa ntchito torque mode, ndikwabwino kugwiritsa ntchito liwiro kapena mawonekedwe. Ngati woyang'anira alendo ali ndi ntchito yabwino yotsekera-loop, mphamvu yoyendetsa liwiro idzakhala yabwino. Ngati chofunikiracho sichili chokwera kwambiri, kapena palibe chofunikira chanthawi yeniyeni, palibe chofunikira kwambiri kwa woyang'anira wolandila mumayendedwe owongolera.
  3. Kuchokera pakuwona kuthamanga kwa liwiro la servo drive, kuchuluka kwa ma torque mode ndikocheperako, ndipo kuyankha pamayendedwe owongolera ndikothamanga kwambiri; kuchuluka kwa mawerengedwe a malo ndikokulirapo, ndipo kuyankha pagalimoto ku siginecha yowongolera ndikochedwa kwambiri.
  4. Pakakhala zofunikira kwambiri pakuyenda kwamphamvu, mota iyenera kusinthidwa munthawi yeniyeni. Ndiye ngati liwiro la olamulira palokha lili pang'onopang'ono (monga PLC, kapena chowongolera chotsika chotsika), ndiye gwiritsani ntchito mawonekedwe kuti muwongolere. Ngati kuthamanga kwa oyendetsa galimoto kuli kofulumira, mungagwiritse ntchito njira yothamanga kuti musunthire malo ozungulira kuchokera pagalimoto kupita kwa wolamulira kuti muchepetse ntchito yoyendetsa galimotoyo ndikuwongolera bwino (monga olamulira ambiri apakati mpaka apamwamba); ngati pali kuwongolera kwapamwamba kwapamwamba Wowongolera amathanso kuwongoleredwa ndi ma torque mode, ndipo kuzungulira kwa liwiro kumachotsedwanso pagalimoto. Izi nthawi zambiri zimangochitika ndi olamulira apadera apamwamba, ndipo pakadali pano, palibe mota ya servo yomwe imafunikira nkomwe.
