In the Labview platform, investigate the graphic approach to control the gas flow quantity that provided to the fuel cell. First, using the rectangular doublet pulse as testing input signal, by measuring the data of input hydrogen flow and output voltage, we calculate and obtain the parameter estimation for the assumed second order time-delay fuel cell system dynamics by Taguchi method. Next, according to the dynamic characteristics of the obtained fuel cell model, the proper PID controller is designed. Then, the fuel cell dynamics and designed PID controller are implemented in the MATLAB/Simulink environment to perform controlled system simulation. Also, based on the PID control structure, an extra feedward control signal is supplemented to improve the tracking performance for external voltage command.
