The weakly perturbed linear nonhomogeneous impulsive systems in the form Μ‡π‘₯=𝐴(𝑑)π‘₯+πœ€π΄1(𝑑)π‘₯+𝑓(𝑑),π‘‘βˆˆβ„,π‘‘βˆ‰π’―βˆΆ={πœπ‘–}β„€,Ξ”π‘₯|𝑑=πœπ‘–=𝛾𝑖+πœ€π΄1𝑖π‘₯(πœπ‘–βˆ’),πœπ‘–βˆˆπ’―βŠ‚β„,π›Ύπ‘–βˆˆβ„π‘›, and π‘–βˆˆβ„€ are considered. Under the assumption that the generating system (for πœ€=0) does not have solutions bounded on the entire real axis for some nonhomogeneities and using the Vishik-Lyusternik method, we establish conditions for the existence of solutions of these systems bounded on the entire real axis in the form of a Laurent series in powers of small parameter πœ€ with finitely many terms with negative powers of πœ€, and we suggest an algorithm of construction of these solutions.
