Abstract :
Conventional erbium-doped fiber amplifier (EDFA) control schemes lack a systematic design approach and do not consider the characteristics of input disturbances. We propose the application of H infin control to suppress cross-gain modulation effects due to pilot tones and network burst-switched traffic. A detailed design of the EDFA Hinfin controller is given, focused on input disturbance characteristics and desired performance measures. Simulation results under different types of disturbances show significant improvements in response time and power excursion reductions
