Quasioptimal stabilization of the linear controlled singularly perturbed systems with delay
(V. M. Glushkov Institute of Cybernetics of National Academy of Sciences of Ukraine, Kamianets-Podilskyi Ivan Ohiienko National University, 2024-06-28)We consider a linear singularly perturbed system of difference-differential equations with control. We obtain a representation of an integral manifolds of this system. We search the solution of the problem of quasioptimal ... -
