Ivanets S. Pulse systems of stabilization direct current voltage with fuzzy regulators

Object of research is pulse system of stabilization of a direct current (DC) voltage with a fuzzy regulators (FR). The purpose of research: development of methods and algorithms of increase of quality of stabilization of electrotechnical systems with pulse-width transformation, reduction of instability at disturbance on loading, increase subgarmonic of stability and speed on the basis of use of adaptive and fuzzy regulators. Methods of research: the theory of electrical circuits, theory of a pulse systems, method of a phase plane, method of Z-transformation, fuzzy logic, mathematical and physical modeling. Theoretical and results: the algorithm of definition of a zone of modulation for an adaptive regulator is developed; the method of adjustment FR with use of a phase portrait of system is developed; the increase of a range subgarmonic of stability of pulse system of stabilization is proved at the expense of use of adjusting inclusion of fuzzy and adaptive regulators; the adaptive regulator with the determinant of zones of modulation is developed and practically is realized together with FR in pulse system of stabilization. A subject and degree of introduction: are used in educational process CSTU and are recommended for use in development JSC "Kchimtectilmash", JSC "CеZaRa", Chernigov. Efficiency of introduction: increase of parameters of quality of stabilization of a DC voltage. Sphere of use: systems of stabilization of a DC voltage.
