Abstract:

Stability for periodic linear systems is studied by a new method based on ideas and approaches of commutator calculus. The study of stability for periodic linear system of differential equations is reduced to the study of stability for a periodic linear system with constant coefficients and impulse response.

Sufficient conditions of asymptotic stability are obtained for the initial periodic linear system. They are based on a theorem of the Lyapunov direct method for differential equations with impulse response. Asymptotic stability is also studied for a periodic linear system under small violations of the Lappo-Danilevskiĭ conditions.
