Abstract
An adaptive synchronous machine controller that minimizes a cost function incorporating system input, output, and set-point variations, and its application to a multimachine power system are described. The control is based on a criterion of automatically shifting the closed loop poles of the system towards the origin in the z-domain without violating the control constraints. It possesses the property of robustness and ease of reference signal tracking. The ability of the proposed controller to damp multimode oscillations is investigated. Studies show that the proposed controller cooperates with the conventional power-system stabilizers on the system in damping the oscillations.<>Keywords
