抄録

In the most of the study of the stability problem in inverter-induction motor drive systems, the stability at the equilibrium point has been assumed to be globally stable in the whole system. Induction motor drive systems, however, inherently have a nonlinear nature. In this paper, two nonlinear phenomena in the system are studied by numerically integrating the equation describing the system. One of them is a chaos, that occur in the system having ordinary values of the motor parameters. Another nonlinear effect is existence of two or more attracters at the same system parameters, whitch is the very important fact to the system design and operation. Namely, it means that the trajectry may converge to oscillatory solutions at parameters of the system having a stable equilibrium point. Regions in the parameter space for such nonlinear effects are shown.
