Abstract :
We extend the results of our previous work (2005) to increase the robustness of an L2 nonlinear controller applied to an erbium doped fiber amplifier (EDFA). We consider the rejection of input and state uncertainties to a full information (FI) extended state space model of the EDFA. The generic robust stabilization problem is solved and the concept of state uncertainty is shown to be associated to parametric uncertainty in the EDFA model. We compare the improved robust L2 controller to the standard L2 controller in our previous work (2005)
