Iyo Ultrasonic Cake Cutter inosvika sei nekukurumidza uye chaiyo chinzvimbo chezvigadzirwa? Mhinduro ndeiyi: servo control. Saka, chii chinonzi servo control?

 

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. Iyo servo system inogona kukamurwa kuita zvinhu zvinotevera:

  1. Raira chikamu: chinobuda mudziyo wechiito chekuraira chiratidzo
  2. Dhiraivha chikamu: chishandiso chinogashira kuburitswa kwechikamu chekuraira uye chinotyaira chiito cheactuator (senge mota)
  3. Feedback chikamu: chishandiso chekuona chimiro chekuuraya kana mamiriro ekuremedza
  4. Actuator: Gamuchira chiratidzo chinobuda chechikamu chekutyaira kugadzira torque, chinzvimbo uye dzimwe nyika

 

2. Chimiro chemukati che servo:

 

3. Kudzora nzira

Kazhinji, servo ine matatu ekudzora modhi: kumhanya kudzora modhi, torque control mode, uye chinzvimbo chekudzora maitiro.

 

4. Kuenzanisa nzira nhatu dzekudzora:

  1. Kana pasina chinodiwa pakumhanya uye chinzvimbo chemota, chero bedzi torque inogara ichibuda, iyo torque modhi inoshandiswa.
  2. Kana paine chimwe chechokwadi chinodiwa chechinzvimbo uye kumhanya, asi kwete kunyanya kunetseka nezve chaiyo-nguva torque, hazvina kunaka kushandisa torque modhi, zviri nani kushandisa kumhanya kana chinzvimbo modhi. Kana iyo host controller ine zvirinani yakavharwa-loop control function, iyo yekumhanyisa kudzora maitiro ichava nani. Kana chinodiwa chisina kunyanya kukwira, kana pasina chaicho chinodikanwa chenguva-chaiyo, hapana chinodiwa chepamusoro kune mutongi wevaenzi mune chinzvimbo chekutonga modhi.
  3. Kubva pakuona kwekumhanya kwekupindura kweservo drive, iyo torque mode calculation chiyero idiki, uye mhinduro yedhiraivha kuchiratidzo chekudzora ndiyo inokurumidza; iyo position mode calculation amount ndiyo yakakura, uye dhiraivha yekupindura kune control signal ndiyo inononoka.
  4. Kana paine zvakati wandei zvinodikanwa zvesimba rekuita mukufamba, mota inoda kugadziridzwa munguva chaiyo. Zvino kana kumhanya kwekushanda kwemutongi pachawo kunonoka (senge PLC, kana yakaderera-yekupedzisira motion controller), saka shandisa iyo chinzvimbo modhi kudzora. Kana kukurumidza kwekushanda kwemutongi kuri kukurumidza kukurumidza, unogona kushandisa speed mode kuti ufambise loop yenzvimbo kubva mudhiraivha kuenda kune controller kuti uderedze basa redhiraivha uye uvandudze kushanda zvakanaka (zvakadai semazhinji epakati-kusvika-yepamusoro-yekupedzisira motion controllers); kana pane zviri nani kutonga kwepamusoro Mutongi anogona zvakare kudzorwa ne torque mode, uye iyo yekumhanyisa loop inobviswawo kubva mudhiraivha. Izvi zvinowanzoitwa chete nepamusoro-yekupedzisira akakosha controller, uye panguva ino, hapana servo mota inodiwa zvachose.
