Energy generation system behaviour using a clocked fuzzy peak current control

In this paper is analyzed by simulations the nonlinear phenomena in the boost converter used as power interface into the energy generation system (EGS). Transition to chaos in one or more stages depends on the initial conditions and the bifurcation diagrams with the reference current as the variable parameter have been reported. The simulation results show that the EGS without large energy storage device (ESD) shift to chaos as the parameter is modified. Two kind of the peak current controller are used. The proposed fuzzy peak current controller provides better dynamic response, robustness against system uncertainty disturbances, and an implicit stability proof.
