Veligorsky O. Stabilizer of direct current voltage with digital adaptation to kind of pulse-width modulation

Object of research is pulse system of stabilization of a direct current (DC) with loading of the second order. The purpose of research: upgrad-ing stabilization of output voltage of pulse system of stabilization due to alteration of the PWM prospects and account of chaotic processes. Methods of research: the theory of electrical circuits, fundamental theory of the linear and nonlinear impulsive systems, theory of approximation, method of Z-transformation, mathematical and physical modeling, theory of bifurcation and catastrophes. Theoretical and results: it is set that the systems of stabilization, executed on principle of the inferior ad-justing with the internal contour of current, have more high dynamic and static indexes of exactness, than systems with asynchronous integral PWM; it is set that systems with two-sided PWM in a dynamics have the minimum root-mean square error of adjusting as compared to PWM back and front fronts; it is set that the system of stabilization is most sensible to the perturbance on the feed at approach to the points of bifurcation, and practically unsensible to them after these points; the system of stabilization of DC voltage is created with reconstruct of the PWM. A subject of research: process in DC stabilizer, precision optimization of control system. 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.
