Performance Enhancement of Solid Oxide Fuel Cell by Employing PI Controller and PID Controller with Filter Derivative

Solid oxide fuel cells (SOFCs) are effective electro-chemical devices that directly convert chemical energy into highly efficient, low-pollution electrical energy. However, high operating voltage and rapid fluctuations of the load disruption of SOFC system addresses challenges in controlling the output voltage. The objective of the paper is to improve the performance of SOFC system by employing PI controller and PID controller with filter derivative (PIDF). PID tuner is used to optimize the controller gains of the PI and PIDF controller. The output of the SOFC system with PI and PIDF controller are being compared. Simulation result shows that output obtained from PIDF controller is superior to PI controller.
