Design and simulation of fuzzy controller for PEMFCs

There are many successful applications of fuzzy controller for nonlinear processes. Operations of proton exchange membrane fuel cells (PEMFCs) are time-varying nonlinear processes. Fuzzy control as an effective control technique is applied for the control of PEMFCs in this work. In order to implement design and analysis of fuzzy controller, a dynamic PEMFC model is developed. Then using this model, a fuzzy controller is introduced to control the output voltage of a PEMFC. Simulation results of PEMFC voltage behavior at different load conditions confirm the high performance capability of the designed fuzzy controller
