Abstract
This
paper has numerically studied the dynamical behaviors of a fractional-order
single-machine infinite-bus (FOSMIB) power system. Periodic motions, period- doubling
bifurcations and chaotic attractors are observed in the FOSMIB power system.
The existence of chaotic behavior is affirmed by the positive largest Lyapunov
exponent (LLE). Based on the fractional-order backstepping method, an adaptive
controller is proposed to suppress chaos in the FOSMIB power system. Numerical
simulation results demonstrate the validity of the proposed controller.
