Study on Adaptive Control of PEMFC System

It discussed the modeling of the PEMFC, air supply system and hydrogen supply system. Then the discrete-time model reference adaptive control (MRAC) is applied in air supply system, and PID control in hydrogen supply system. By adjusting the supply mass of oxygen and hydrogen, the output voltage and the pressure of hydrogen and oxygen could be satisfied with the system demands. The results of simulation show that the control system has good dynamic performance, is satisfied with the control demands.
