Abstract

In this paper, a robust nonlinear control scheme based on the combination of the block-control linearization and integral sliding modes is proposed. This control technique is applied to multimachine electric-power systems. The plant model takes into account the interactions in power systems between the electrical and mechanical dynamics and load constraints. A nonlinear observer is designed to estimate the synchronous generators´ rotor fluxes. The proposed control scheme requires only local information of each generator. The considered controller was tested and compared with a classical one through simulation on the Western System Coordinating Council system.
