Abstract: The fuel cell robot hybrid power system is a multiple-input and multiple-output nonlinear system. This paper established a model for the system using neural network model, and model predict control strategy was used to control energy split of the system. The simulation results show that the description of neural network has higher precision and good ability of global approximation.

Abstract: In this paper, the single-phase synchronization inverter of fuel cell is taken as the main topic. The network system topology, the control strategy and the phase-locked algorithm are analyzed in detail. The system’s main circuit topology, the software PLL principles and process are proposed, and they are verified by the experiments.
