Study on an adaptive multi-model predictive controller for the thermal management of a SOFC-GT hybrid system

A SOFC temperature control system based on adaptive multimodel predictive (MMPC) method is designed for a solid oxide fuel cell-gas turbine (SOFC-GT) hybrid with anode and cathode ejectors. Two multi-input multi-output MPCs (under 100% 90% load) are to the inlet temperatures. The accuracy of identified linear models both more than 95%. performance MMPC compared single MPC traditional PI. comparison results demonstrate that proposed most effective competitive in thermal management. During load following, controller overshoot less 1.19K. settling time about 2000s, integral time-weighted absolute error 472.
