In this paper, a linear optimal controller design with regional pole placement is proposed and employed on a power system model especially for damping electromechanical oscillations. The method utilizes a theorem which relates the weighting matrices of a linear quadratic optimal system to the bounds of the closed-loop eigenvalues defined 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.
