2-laboratoriya ishi avtomatik boshqarish tizimlarning vaqt xarakteristikalarini tadqiq etish

Simulink Library Browser oynasining qidiruv satriga elementlarning nomlarini yozish orqali ularni topib, hosil qilingan oynaga 3.1-rasmda keltirilgan sxemani yig„ing.

3.1-rasm. Birinchi darajali aperiodik zvenoning

MATLAB dasturidagi modeli

5. 
   Andozali zvenoning parametrlarini o„rnatish uchun “sichqoncha”ning chap tugmasini zveno sxemasi (Transfer Fcn) ning ustiga 2 marta bosilsa Block paramtres:Transfer Fcn paneli chiqadi va bu panel orqali zvenoning parametrlari (kuchaytirish koeffitsiyenti K=3 va doimiy vaqt kattaligi T=0.3 sek) o„rnatiladi (3.2-rasm).
   

3.2-rasm. Block paramtres: Transfer Fcn paneli

6. 
   Natijada taxlil qilinayotgan zvenoning aniq parametrlari keltirilgan model hosil bo„ladi (3.3-rasm).
   

3.3-rasm. Birinchi darajali aperiodik

zvenoning
parametrlari belgilagan modeli

7. 
   Barcha parametrlar belgilangandan so„ng bosh menyudan Simulation\Start (yoki Ctrl+T) tugmasi orqali modelni ishga tushiring va
   

“sichqoncha”ning chap tugmasini Scope ning ustiga 2 marta bosib ekranga zvenoning o„tish

jarayonini quring. Natijani (3.4-rasm) File\Print to Figure tugmalarini bosib printerdan chiqarib oling.

8. 
   O„tish jarayonining egri chizig„ini ekranga moslab chiqarish uchun „Scope‟ panelidan
   

Autoscale tugmasi bosiladi va Parameters tugmasini bosib o„tish jarayoni vaqti belgilanadi, masalan 2 sekund (3.5-rasm).

9. 
   Zvenoning impulsli o„tish jarayonini qurish uchun yangi oyna oching (File >>New>>Model yoki Ctrl+N) va 3.6-rasmda keltirilgan sxemani yig„ing.

impulsli o„tish jarayonini qurish uchun tuzilgan modeli

10. Zvenoning		parametrlari		5-bandda
ko‟rsatilganidek belgilab olinadi, ya`ni K=3;
T=0,3	sek.	Barcha		parametrlar
