Sitnikov V. Theoretical and realization bases of creation of linear digital frequency-dependent converters with the regulated accuracy for control systems

The dissertation is devoted to creation and realization bases of the analysis and construction, and also technical realization of digital frequency-dependent converters with regulated accuracy (DFCRA) with the advanced properties and the set limitations for control systems which provide to the work of the converter at the set errors of frequency characteristics in a working frequency range, and also to realization of these converters on structural diagrams with a minimum level of round-off noise. Offered theoretical and realization bases are based on methods of formation of description DFCRA, the control of a level of round-off noise and formation of the structural organization that assisted in regulation of accuracy of converters and increase the efficiency of control system. Correction of elementary component making due to the corrector allows to receive quasiideal frequency characteristics DFCRA. Depending on a task which solve also requirements to frequency characteristics the variant and a methodof correction is selected. For decrease in a total level of round-off noise the complex method to its analysis and estimations is offered. The method of decrease in a total level of round-off noise for realization DFCRA of the high order and is offered toa choice of the structural organization of the converter with a minimum level of round-off noise in a working frequency range.
