pH titrasyon eğrilerine durum-uzayı yaklaşımı

Çevresel problemler her geçen gün artan bir eğilim göstermektedir. Bu problemlerin artmasının başlıca sebeplerinden bir tanesi kimyasal proseslerin sağlıklı kontrol edilememesi ve modern kontrol tekniklerinin kullanılamaması olarak gösterilebilir. Bunun nedeni, kimyasal proseslerin durum uzayı ve/veya transfer fonksiyonu yapısına alınamamış olmasıdır. Lineer sistem teori yardımı ile durum uzayı ve/veya transfer fonksiyonu elde edilebilir. Durum-uzayına ulaşmak için kimyasal eşitlikler ve matrisyel formasyon yeterli olacaktır. Sistem matrisinin asit konsantrasyonu için alternatif taşıyıcı ile kare matris boyutlarına alınması sayesinde transfer fonksiyonu elde edilir. Bu çalışmada bahsi edilen yaklaşımı onaylamak için zayıf asitkuvvetli baz reaksiyonu ele alınmıştır. Sayısal veriler ve benzetim sonuçları yeni yaklaşımı onaylamaktadır. Modern kontrol yaklaşımlarının kimyasal süreçlere uygulanma yolu açılmıştır.

State-space approach to pH titration curve

Environmental problems have positive slope and this position goes to worse point day to day. Other side sensitive chemical processes can not be controlled by modern controllers. Because chemical process modelling was not translated into a transfer function or a state-space representation. System theory can be utilized for this purpose. To create a state-space presentation, chemical equations and matrix formation are combined. An alternative carrier signal is applied on acid molarity to create a square form system matrix, and then transfer function can be obtained. To validate novelty, the new approach is applied to weak acidstrong base neutralization process. Obtained simulation results shows that the algorithm have an effective performance and ways of modern control theories are opened to chemical procesess.
