Thermoelectric power generation using the thermoelectric power generation element is now being developed as one of the future power generation systems by thermal energy. However, the system has some problems of improving the generating efficiency. In this paper, an operator-based nonlinear control system for the thermoelectric power generation system is proposed. Firstly, structure of the thermoelectric power generation system is introduced. Secondly, the thermoelectric power generation system is modeled and the proposed system based an operator-theory is designed by using the model. Finally, the effectiveness of the proposed control system is confirmed by simulation results and experimental results.

In this paper, an operator-based nonlinear control system for a polymer electrolyte fuel cell (PEFC) reformer is proposed. Firstly, structure of the reformer is introduced and modelled. Secondly, an operator-based nonlinear control system for the reformer is designed by using the model. Here, uncertainties which are assumed ΔP are considered. And the desired performance of temperature tracking is discussed. Finally, robust stability analysis and the effectiveness of the proposed control system are confirmed by simulations.
