Abstract

A 300 kW solid oxide fuel cell gas turbine (SOFC-GT) power plant simulator is evaluated with the use of a model reference adaptive control (MRAC) scheme, implemented for a set of nonlinear empirical transfer functions. The SOFC-GT simulator allows testing of various fuel cell models under a hardware-in-the-loop configuration that incorporates a 120 kW auxiliary power unit and balance-of-plant components in hardware, and a fuel cell model in software. The adaptation technique is beneficial to plants having a wide range of operation, and strong coupling interaction. The practical implementation of the adaptive methodology is presented through simulation in the Matlab/Simulink environment.
