The problem of complete controllability of a linear time-invariant singularly-perturbed system with multiple commensurate non-small delays in the slow state variables is considered. An approach to the time-scale separation of the original singularly-perturbed system by means of Chang-type non-degenerate transformation. generalized for the system with delay. is used. https://www.mojozers.shop/product-category/air-pulsation-premium/
