Electrochemical Impedance Spectroscopy Measurement Method for Fractional-Order Delay System Based on Model Predictive Control
Electrochemical impedance spectroscopy (EIS) plays a crucial role in fuel cells (FCS) and can reflect the health status of fuel cells. The measurement of fuel cell EIS can apply ripple modulation on the control side of the DC/DC converter to obtain the ripple of the fuel cell output voltage and current. In practical control systems, since sampling is often a fractional-order delay, we have added a fractional-order delay compensation in the EIS measurement system. The experiment shows that this method can effectively solve the EIS of fuel cells.
