Abstract :
Applying Popov´s stability criterion to the correct transfer function for the system studied in the work P.B. Anjaneyulu et al. (see ibid., vol.IE-31, no.2, p.175-80, (1984)), suitable conditions for stability are derived. From these conditions, the stability region obtained is larger than that given in the mentioned work. These results can be verified by using Lyapunov´s second method.<>
