Abstract: | Most of the controllability concepts are for first ordered differential equations, while
not all the control systems are of this kind; but by increasing the dimension of the
state space, one can rewrite the control system in the form of first ordered differential
equations. Therefore, it seems useful to define partial controllability concepts which
maintain the original state space. In this thesis, a sufficient condition for partial approximate
controllability of semilinear deterministic control systems is proved with a
technique which is completely different from the methods using fixed point theorems.
More specifically, the partial S-controllability has been weakened for partially observable
semilinear stochastic systems and a sufficient condition is provided. The results
obtained are demonstrated within examples.
Keywords: Controllability, approximate controllability, exact controllability, partial
controllability, semilinear systems, stochastic systems. ÖZ:
Kontrol edilebilirlik kavramlarının ço˘gu, birinci dereceden diferansiyel denklemlerı
içeren kontrol sistemleri için formüle edilmi¸stir. Do˘gadaki bütün diferansiyel denklem
sistemleri bu tür de˘gildir, ama alanın boyutunu geni¸sleterek bu formda yazılmı¸s
olabilir. Bu nedenle, orijinal alanı korumak kısmi kontrol edilebilirlik kavramları
tanımlamak yararlı görünüyor. Bu tezde, yarı-lineer deterministik kontrol sistemlerinin
kısmi yakla¸sık kontrol edilebilirlik için yeterli bir ko¸sul, sabit nokta teoremleri
yöntemlerinden tamamen farklı bir teknik ile kanıtlanmı¸stır. Dahası, kısmen gözlemlenebilir
yarı-lineer stokastik sistemleri için zayıflatılmı¸s kısmi S-kontrol edilebilirlik
incelenmi¸s ve bu kontrol edilebilirlik kavramı için yeterli bir ko¸sul sa˘glanmı¸stır. Elde
edilen sonuçlar, örneklerle gösterilmi¸stir.
Anahtar Kelimeler: Kontrol edilebilirlik, yakla¸sık kontrol edilebilirlik, tam kontrol
edilebilirlik, kısmi kontrol edilebilirlik, yarı-lineer sistemler, stokastik sistemler. |
