Abstract :
A structure singular value (SSV) μ synthesis control strategy based on D-K iteration method was proposed to conquer unstructured and structured perturbations for a proton exchange membrane fuel cell (PEMFC) generation system. The D-K iteration method was utilized to solve the proposed controller by combining a standard H∞ optimization problem and a convex optimization problem at each frequency. The simulation results demonstrated that the control method could maintain the oxygen excess ratio better at the optimal operating point and guarantee stable operation of the system when the vehicle running process was simulated. The comparison with H∞ control strategy verified that the proposed method had better robust stability and robust performance.
