碩士 === 高苑科技大學 === 電機工程研究所 === 98 === This thesis is on the study of dynamic model and controller design of the proton exchange membrane fuel cell (PEMFC) in the PC-based structure. By using MATLAB/Simulink, the fuel cell is represented by second order differential equation with time delay. The simulation is conducted for the PEMFC with four parameters to be determined. First, based on the chosen ranges of varying parameters, the combinations of parameter values are substituted into the numerical model. There are three experiments investigated in this thesis. The first one considers a single temperature and current operation condition. By using Taguchi method, the optimal parameters estimation is obtained and verified. In the second experiment, multiple conditions with different operation temperature and current are considered. The same Taguchi method as for experiment one is used for parameters estimation. In the third method considered the same multiple operation conditions as in experiment two, the fuzzy Taguchi method for multi-objective index for minimization of both the absolute error integration and maximum error integration is conducted. According to the obtained results, the second and third can obtain the same optimal parameters estimation in this study.
