Analysis of subsystem integration in aircraft power distribution systems

Stability analysis of a baseline power system architecture for modern aircraft is addressed. Power electronic converters are widely used in modern aircraft power distribution systems. Due to their inherent nonlinear characteristics, instabilities may arise while integrating individual subsystems together. Bifurcation analysis is used to identify the type, multiplicity and stability of system trajectories. The complete bifurcation diagram for the baseline power system is drawn. The dependence of the parameter values on the bifurcation behavior of the baseline system is presented.
