چکیده:

Design of an optimal nonlinear state feedback voltage regulator for power systems isproposed in this paper. In order to obtain the nonlinear control law the Hamilton-Jacobi- Belman (HJB) equation is solved using Taylor series expansion of its nonlinear terms. The performance of the proposed controller in a single machine-infinite bus power system is simulated and the advantages of the nonlinear feedback controllers in some
grounds like increasing the fault tolerance and domain of validity of the close-loop system are investigated. Also, the advantages of the proposed controller in the presence of some disturbances are shown. Simulation results reveal the effectiveness of the proposed controller.
