“…In [6] an online self tuning PID controller for PEM fuel cell systems is described. However, from the literature it can be seen that the fuzzy controller design is widely used for performance enhancement in fuel cell systems; see for example, [7], [5], [8], [9], [10]. In [11] for a SOFC, a control strategy using fuzzy logic controller to effect voltage control of the fuel cell at the output of the DC/DC converter is presented.…”
