Abstract:

Current control methods for Erbium doped fiber amplifier (EDFA) devices lack a systematic approach to provide specified performance over the entire state space. Linearization techniques are combined with heuristic switching to attain operation around specific operating points. In this paper, a more inclusive model that takes amplified spontaneous emission (ASE) into account is developed. Furthermore, a nonlinear L2 control scheme is developed that eliminates the necessity of switching between multiple linear control approximations and replaces them by one nonlinear controller that is valid over the entire state space (or average inversion level)
