Servo Control Applıcatıon Of Predıctıve Algorıthm To The Cheese Whey Drınk Productıon

Peyniraltı suyu (PAS) ile bir tür içkisi; PAS, glikoz,üzüm suyu ve sütten oluşan pastörize karışımdan üretilmiştir. Kesikli bir biyoreaktörde kefir mayası ile bu karışımın fermentasyonu araştırılmıştır. Peynir altı suyu içkisi üretimi sırasında pH değerleri kaydedilmiştir. Genelleştirilmiş öngörmeli kontrol (GPC) algoritması için sistem modeli deneysel veriden yararlanarak elde edilmiştir. pH set noktasına basamak etki verilmesi durumunda (yani servo kontrol durumunda) GPC teorik olarak biyoreaktöre uygulanmıştır. N2=2, Nu=1, λ=0.007 ayar parametreleri ile GPC iyi servo kontrol sonucu sağlamıştır.
