analysis and method of Lyapunov for evaluate the limits of the small signal models and suggest to utilize models that can permit the analysis of the system when subjected to a severe transient disturbance.
In this paper works with no-lineal tool and computer simulations, phase-plane trajectory analysis and method of Lyapunov for evaluate the limits of the small signal models and suggest to utilize models that can permit the analysis of the system when subjected to a severe transient disturbance.
