Abstract:

This paper investigate the finite gain stabilization problem of the singlemachine infinite bus system subject to actuator

saturation and input additive external disturbances. Based on Hamiltonian energy theory, this paper first transforms the power

system model into a general Hamiltonian system model with dissipation. Then a static output feedback controller is considered

for the obtained Hamiltonian system. Under some growth conditions, it is shown that the asymptotic stabilization, as well as the

finite gain stabilization of the closed loop systems can be achieved. In establishing the results, an estimate of the finite

gain is also obtained. Simulation shows the effectiveness of the stabilizing method proposed in this paper.
