Abstract
The purpose of this thesis is mainly to simulate the 100W fuel cell system through the software, EASY5. The transfer function of the fuel cell system obtained through system identification is used to design the robust controller and PI controller, and compare the simulation results of the two controllers.
First, the related parameters of the 100W fuel cell system are set in EASY5, and the transient and steady state characteristics simulated through EASY5 are compared with the experimental results. Next, the transfer function of the 100W fuel cell system is obtained through the system identification done in EASY5, and it is used to design the robust controller and PI controller. The method of designing robust controller is loop shaping. Finally, compare and discuss the simulation results of the two controllers. The result is that the robust controller not only improves the transient response of the fuel cell but tracks the reference command even if the current varies.
