Abstract
Proton Exchange Membrane Fuel Cell (PEMFC) temperature exists complex nonlinearity and is deeply disturbed by load change. Considering the characteristics of PEMFC temperature control, an improved fuzzy-immune PID algorithm is derived based on the immune feedback regulating law. Compared with general fuzzy-immune PID algorithm, radial basis function (RBF) neural network is introduced to the on-line optimization work of fuzzy-immune PID parameters, which optimizes the PID parameters on-line. Simulation results show that the proposed method in this study achieves good performance in temperature control and is useful for wide application of PEMFC.
