Performance Analysis of Fuel Cell Based Boost Converter Using Sliding Mode Controller

Fuel cell are most promising devices for all types renewable energy harvesting for both on grid and off grid distributed generation systems. The vital usage of this fuel cell is mainly due to its modularity, better potential capability and minimal maintenance. But its performance needs to be controlled under varying load conditions (uncertainty) due to which system's stability get affected. In this paper, sliding mode controller is used for controlling the fuel cell output under various circumstances of uncertainty in order to attain the asymptotically stable system. This designing of sliding mode controller evidently improves the stability and its results are obtained with the help MATLAB SIMULATION and stability improvements is been captured by analysis. Further the output and efficiency of both PID controller and sliding mode controller (SMC) is being compared and simulation result indicates that SMC is superior than PID in terms of reducing disturbances and improving the overall stability and efficiency of proton exchange membrane fuel cell (PEMFC)model.
