Induced Chaos in Speed Controlled Switched Reluctance Motor Drive

In this paper the occurrence of chaos in the hysteresis-controlled switched reluctance motor (SRM) drive under phase current saturation is examined. An 8/6 pole 4-phase SRM is used as the model for this study. To gain insight into this phenomenon, the analytical modelling of the SR drive system is derived and triggering condition for chaotic behaviors is discussed. The simulation and experimental analyses are conducted to uncover the underlying pattern of chaotic motion within this type of motor drive system.
