    Extremum seeking control of cascaded Raman optical amplifiers
    Dower, PM ; Farrell, PM ; Nesic, D (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008-05-01)
    This paper considers the control of a particular type of optical amplifier that finds application in long-haul wavelength division multiplexed optical communications systems. The objective of this consideration is to demonstrate an application of extremum seeking to the regulation of amplifier output signal power across a range of signal wavelengths, where limited control authority is available. Although such amplifiers are nonlinear and distributed parameter devices, an extremum seeking design is demonstrated to be a promising approach for achieving the stated amplifier control objectives.
