Analysis of bifurcation in power electronic induction motor drive systems

Instability phenomena in power electronic induction motor drive systems are investigated from the point of view of bifurcation theory. A method to determine bifurcation values of system parameters is discussed. It is shown that some kinds of bifurcations are observed in power electronic induction motor drive systems. The proposed method makes it possible not only to determine instability regions of system parameters, but also to investigate qualitative properties of the instability phenomena.<
