Abstract :
A backstepping controller design is proposed for the load voltage tracking of electric power system. It is known that a power system might exhibit saddle-node and Hopf bifurcations as load change, which can lead to the appearance of dynamic and/or static voltage collapses. The output tracking control laws are proposed for the load voltage regulation of the electric power system via backstepping control scheme. The numerical simulations demonstrate that the proposed control scheme not only could provide the regulation of the load voltage but also prevent and/or delay the appearance of bifurcation phenomena and chaotic behavior.
