Abstract

—Power systems stability is enhanced through a novel stabilizer developed around a non singular adaptive fuzzy terminal integral sliding mode approach using the Nussbaum function applied to a nonlinear model of a single machine power system connected to an infinite bus via a double transmission lines subjected to severe faults. Nussbaum gain is used to avoid the problem of controllability of the system. Stability is insured through Lyapunov synthesis. Severe operating conditions are used in a simulation study to test the validity of the proposed method, indicating better performance and satisfactory transient dynamic behavior
