WebJun 29, 2024 · The stability criterion of Routh-Hurwitz is a requirement and an effective stability condition. If any control system does not fulfill the requirements, we may conclude that it is dysfunctional. Nonetheless, the control system may or may not be stable if it meets the appropriate criteria.
