Abstract

In this paper, a linear optimal controller design with re gional pole placement is proposed and employed on a power system model especially for damping electrome chanical oscillations. The method utilizes a theorem which relates the weighting matrices of a linear quadratic opti mal system to the bounds of the closed-loop eigenvalues deļ¬ned by two half-circles in the complex half plane. The method also involves shifting real parts of the eigenvalues associated with selected modes so that a desired damping is also guaranteed.
