A SMC-Based MPPT Controller for Proton Exchange Membrane Fuel Cell System

fuel cells are the most promising technology due to their high power density, low operating temperature, rapid starting capabilities, and low weight. These benefits have led to the PEM fuel cell being used in a variety of applications, including automotive power sources, portable power, and backup power. However, the PEM fuel cell has various issues due to the output power's dependence on operational conditions such as cell temperature and membrane water content. Changes in operating conditions proton exchange membrane fuel cells (PEMFCs) must be kept running at a high enough power by using the MPPT. the goal of this work is to extract the maximum power point to this end a control technique of a maximum power point tracking (MPPT) controller was developed based on sliding mode. The suggested MPPT has been developed and validated on a PEMFC system that includes a boost that is controlled by the suggested MPPT and supplies a resistive load. The proposed MPPT controller was compared to the sliding mode controller in simulations using the Matlab/Simulink tool. Moreover, the MPPT efficiency during rapid temperature variations is calculated using a simple test with varied values. Here are some examples of findings that demonstrate the efficacy and robustness of the proposed controller under non-uniform conditions (temperatures). The designed controller, which is significantly superior than sliding mode controller, effectively achieves rapid response and precise tracking to the maximum power point (MPP) with a significant reduction in the time response and maximum power extracted.
