Abstract
In this paper a comparative study of two pump control schemes for suppressing transient gain excursions in EDFA’s is presented. The first control scheme is based on the traditional feedforward/feedback control, while the second scheme is new and uses multiplication to combine the feedforward and feedback blocks. The controller parameters are designed using linearised (small-signal) EDFA model derived from the nonlinear state-space model of Bononi and Rusch. When the controller design is applied to the nonlinear EDFA plant, the new scheme is shown to display some important performance improvements over the traditional scheme.
