Original Abstract

In the past few years, nonlinear phenomena have been thoroughly investigated in many power converters, but the results are available only in research papers, often written in language accessible only to specialists in the field. Although most feedback control schemes in electric drives (power electronics) have nonlinear aspects, the conscious application of the methods developed in nonlinear control theory to power converter is somewhat more recent. Chaotic behavior in PWM-based electrical drive with cascade closed-loop control is analysed. It is shown that such a system exhibits chaos for a wide range of parameters variations. By means of numerical computation several types of system behavior are studied and corresponding bifurcation diagrams are derived. The diagrams that reflect system behavior depend on two bifurcation parameters have been calculated as well. The corresponding phase orbits and time-domain plots are presented. The results may be of interest to scientists and engineers who deal with high-accuracy electromechanical systems and electric drives.
