Partially Exact Controllability of Semilinear Heat Exchanger Systems
Ismail Huseynov, Arzu Ahmadova, Agamirza E. Bashirov
In this paper, we study two semilinear systems describing a monotubular and a two-stream heat exchanger. Neither system is exactly controllable; however, for each we specify a subs…
