In this paper, a distributed parameter system expressed as a parabolic partial differential equation governed by a diffusivity control is considered. A modal space expansion approach is used to convert the distributed parameter system into a lumped parameter system. Thereafter, Pontryagin’s maximum principle is used to compute the optimal control function that leads to a nonlinear two-point boundary value problem (TPBVP). An iterative numerical technique, variation of extremals is used to solve the nonlinear TPBVP. The feasibility and applicability of the proposed solution is demonstrated by numerical simulations generated in MATLAB.

Bu çalışmada, yayılım kontrolü ile yönetilen parabolik kısmi diferansiyel denklem olarak ifade edilen dağıtılmış bir parametre sistemi ele alınmıştır. Dağıtılmış parametre sistemini toplu bir parametre sistemine dönüştürmek için bir özfonksiyon genişletme yaklaşımı kullanılmıştır. Bundan sonra, Pontryagin'in maksimum prensibi, doğrusal olmayan iki noktalı sınır değeri problemine yol açan optimum kontrol fonksiyonunu hesaplamak için kullanılmıştır. Doğrusal olmayan iki noktalı sınır değer problemini çözmek için, yinelemeli sayısal bir teknik, variation of extremals, kullanılmıştır. Önerilen çözümün fizibilitesi ve uygulanabilirliği, MATLAB'da oluşturulan sayısal simülasyonlarla gösterilmiştir.
