In this paper, based on interconnection and damping assignment passivity-based control approach, a multi-loop adaptive controller for output voltage regulation of a hybrid system comprised of a proton exchange membrane fuel cell energy generation system and a hybrid energy storage system consisting of supercapacitors and batteries, is detailed. The control scheme relies on the design of two control loops, i.e., an outer loop for voltage regulation through current reference generation, and an inner loop for current reference tracking through duty cycle generation. Furthermore, an adaptive law based on immersion and invariance theory is designed to enhance the outer loop behavior through unknown load approximation. Finally, numeric simulation results show the correct performance of the adaptive multi-loop controller when sudden load changes are induced in the system. © 2022 IEEE.
