Optimal State Feedback Control Design and Stability Analysis of Boost DC-DC Converters in Fuel Cell Power Systems Using PSO

This paper presents an intelligent optimal design control strategy for current and voltage of boost DC-DC convertors in fuel cell power systems by considering detailed model for different operating points. The proposed control strategy is designed based on a state feedback whereas the controllability and the stability region are analyzed. Moreover, in order to determine of the optimal coefficients of state feedback and zero steady state error in voltage signal, in the core of the proposed control method a heuristic algorithm namely Particle Swarm Optimization (PSO) is utilized. The results are presented in the different load conditions. In order to show the feasibility of the proposed control strategy, the controller is implemented both average model and detailed model of convertor and the results are compared.
