A saturated sliding mode control scheme for PEM fuel cell power systems
In this paper, a novel adaptive sliding mode controller is designed against the actuator saturation for a PEM fuel cell air feed system. To deal with the saturation nonlinearity, a diagonal matrix with unknown elements is introduced for adaptive design in terms of sliding mode control strategy. An integral type sliding mode surface is designed with constrained conditions. The designed SMC law can guarantee the finite time convergence against the actuator saturation of the plant. The effectiveness of the proposed saturated SMC scheme is validated in the application to air feed PEM fuel cell systems.
