Lead - Lag controllers coefficients tuning to control fuel cell based on pso algorithm

One of the most important Fuel cells (FCs) is Proton Exchange Membrane Fuel Cells (PEMFCs). The output voltage of this FC depends on current loads. This paper tries to introduce, implement and control the voltage of PEMFC, during load variations. The output voltage of fuel cell should be constant during load variation. To achieve this goal, a controller should be designed. Here, the Lead-Lag controller is used which its coefficients are optimized based on PSO algorithms. In order to use this algorithm, first this problem has to be formulated as an optimization problem, including objective function and constraints, and then to obtain the most desirable controller, PSO method is used to solve the problem. Simulation results for various loads in the time domain are performed and the results show the capability of the proposed controller. Simulations show the accuracy of the proposed controller performance to achieve this goal.
