Abstract :
The source of nonlinearity are the hysteresis comparators and dependence of switchings on state variables in direct torque controlled (DTC) induction machines (IM). The nonlinearity generates some strange operation states. They are revealed, analyzed by bifurcation diagram and recurrence plots both in motoring and generating operations.
