Stability of periodic modes in pulse-width systems

The system under study contains one or more sampled-data elements that perform pulse-width modulation of the first or second kind. For case of a stable continuous part of the system simple sufficient conditions are obtained for asymptotic stability in the “small” of simplest periodic conditions in the form inequalities relating the characteristics of sampled-data elements, and of the sampled-data linear part with parameters of the conditions under study.
