The Cascade PI Controller Design for Hydrogen Electric Bike Systems

The paper presents the cascade PI controller

design for a DC/DC converter. The hydrogen is used as the main

energy source feeding to the fuel cell stack in which the voltage

generated from the fuel cell is fluctuated. As a result, the DC/DC

converter is used to regulate the voltage feeding to the electric

bike driving systems. The controller design using the standard

second order system is proposed. The simulation results from

MATLAB/SIMULINK shows that the resulting cascade PI

controller can regulate the voltage even the power load level is

varied. The considered system with the controller designed by

the proposed method can provide the good voltage response

until the rated power can be achieved. The ripple voltage in the

steady state is under 0.5% following the standard ISO-21780-

2020.
