Description
Summary:Results of analysis of dynamic characteristics of a multizone integrating frequency–width–pulse regulator (MR) under the influence of a harmonic interference signal over a wide frequency range for thresholds of the leading relay element are considered in this article. A block diagram of the MR and time diagrams of its signals and amplitude and modulation characteristics, as well as basic relations for their construction, are given. Analysis of the MR behavior with harmonic modulation of switching thresholds of relay element is carried on the basis of the character of the behavior of the MR transmission coefficient and the deviation of the sampling interval of its output pulses from the value by a predetermined control signal. The results of the analysis are presented in the form of the dynamic state space of the MR and logarithmic amplitude–frequency characteristics in the investigated frequency range of harmonic signal interference.
