The paper deals with the linear systems of neutral differential equations with constant coefficients and a constant delay of the form
where , , and are constant matrices, and is a column vector-solution. The authors investigate the exponential-type stability of such systems using Lyapunov-Krasovskii type functionals. Delay-dependent conditions sufficient for the stability are formulated in terms of positivity of auxiliary matrices. Illustrative examples are shown and comparisons with known results are given.
