STATE ESTIMATION OF SOFC/GT HYBRID SYSTEM USING UKF

A description of a Solid Oxide Fuel Cell (SOFC) combined Gas Turbine (GT) hybrid system is given. Modeling of all the components of the hybrid system is briefly presented. A decentralized control structure using PI controllers is designed and is considered as a part of the system. An Unscented Kalman Filter (UKF) is applied to estimate the state vector and the simulation results are presented.
