A research on time delay feedback control performance in chaotic system of DC-DC inverter

Abstract

DC-DC inverter is a strong nonlinear systems, in the course of the parameter changing, the inverter would process period doubling bifurcation, torus bifurcation and saddle-node bifurcation, at last getting in chaotic state embedded with many unstable periodic orbits which will make the inverter turn into the chaotic state from the original stable operation mode. In this paper, in order to overcome the chaotic motion or the random motion in the inverter to eliminate the unstable factors achieving stable mode, we use the delayed feedback control method to realize a useful control of the inverter.
