Description
Summary:In this paper, the analysis of nonlinear dynamic behavior, especially chaotic behavior, in switched reluctance (SR) motors using voltage PWM regulation is carried out. It is identified that the highly uneven distributions of both current and torque of each phase winding during voltage PWM regulation make the SR motor drive prone to chaos. Based on the derivation of the Poincaré map of the SR motor drive, the normal periodic, abnormal periodic, and chaotic behaviors are analyzed by computer simulation. Also, bifurcation diagrams with respect to the speed feedback gain, load torque, and reference speed are presented. These diagrams facilitate the investigation of the route to chaos under different parameters of the drive system.
