STOCHASTIC, FEATURES IN THE DYNAMIC CHARACTERISTICS OF A PULSE-WIDTH CONTROLLED VOLTAGE STABILIZER

The dynamic characteristics of a pulse-width voltage stabilizer are in vestigated by means of a model represented by two-dimensional mapping. The purpose of the investigation is to establish the reasons for the appearance of chaotic dynamic characteristics. Feigenbaum one-dimensio nal mapping is also considered. Along with the well known concept of t he region of attraction, the concept of the inner region of attraction is introduced. It is shown that chaotic dynamic characteristics appea r with certain correlations between the region of attraction radii and the value of random disturbances. Reasons for catastrophic chaos are given, (C) 1996 Elsevier Science Ltd, All rights reserved.
