Abstract: The paper is concerned with control systems with dynamic frequency pulse modulation of an arbitrary form. The modulator is shown to be representable as an equivalent closed-loop system. The structure of this system is found for an ideal and a real modulator. Modulator models are obtained for the cases where a linear filter or a filter with power nonlinearities are used. Examples illustrate the equivalence of a dynamic frequency pulse modulator and its model. The latter is used for design of a calculation automatic model with a dynamic frequency pulse modulator.
