Abstract

In this paper we apply a generalized version of Kharitonov´s theorem to parameter perturbations in the state space description of a power system with a power system stabilizer (PSS). Specifically, the parameters in the PSS controller such as the gain and lead-lag time constants are considered as candidates for perturbations and the region of Hurwits stability is computed via the edge theorem and the segment lemma. A single machine infinite bus example is illustrated
