The functional is constructed for the system with a time-varying delay with a given time derivative, which is calculated on the system trajectory. The presented method gives analytical formulas for the coefficients of the Lyapunov functional.}, type={artykuł}, title={A Lyapunov functional for a system with a time-varying delay}, keywords={Lyapunov functional, time delay system, LTI system}, }
