On modeling and control of advanced aircraft electric power systems: System stability and bifurcation analysis
Equilibrium points of the AAEPS undergo different bifurcation behaviors when changing the systems operating parameters. Movement of eigenvalues across the imaginary axis indicates Hopf bifurcations chaotic motions and oscillatory system. Bifurcation analysis provides the location of the system equilibrium points required for reliable design. The robustness of the system profiles against variations of control parameters was reported in this paper. Parameter values where the system becomes unstable due to a Hopf bifurcation, and oscillation stability margins are given.
