The Impact

This paper presents, a novel controller design technique that can be used for the Proton Exchange Membrane Fuel Cell to tackle the impact of the sudden stack current disturbances. The proposed controller design consists of three components: a full-state feedback control loop, an integral of error control loop and a feed-forward control loop. The feed-forward control loop is designed to ease the impact of the piecewise continuous current disturbance on the stack voltage. Linearized system matrices are set up in such a way that a new augmented system is formed. Controller gains are calculated by using a quadratic performance criterion which is minimized along the trajectories of the augmented system. Simulation results are presented and discussed.
