Summary:In this paper, chaotic behavior in current-mode-controlled dc
drive systems has been analyzed. The key is to derive an iterative map
that describes the nonlinear system dynamics. Analytical modeling of
fundamental and subharmonic oscillations as well as their stability
analysis are presented. The results show that current-mode-controlled DC
motor drive systems generally exhibit chaotic behavior. To avoid the
occurrence of chaos, the stable ranges of various system parameters are
determined. Both computer simulation and experimental measurement are
given to verify the theoretical analysis
