| Abstract |
The main objective of the paper is to highlight the strange behaviour of a class of power electronic system through an example of an induction motor fed by a voltage source inverter
and controlled by tolerance band current controller. The paper presents simulation results for periodic and chaotic states of the system, and studies astonishing properties of transitions between them. Changing some system parameters, various regularities can be discovered. Period
doubling, bend splitting and window periodicity will be presented. Averaged Lyapunov exponent has been calculated. The final aim of this research is to find ways of locking and stabilizing the system trajectories along periodic orbits. |
