Abstract

Redundancy design scheme and control strategy of the energy management system for a stratospheric airship are proposed, which use the coordination control between the photovoltaic cell and lithium battery to maintain the DC bus voltage constant, so as to guarantee the stability of the motor load. The system can switch to corresponding working state according to different conditions through the analysis of the different control modes of unidirectional DC-DC and bidirectional DC-DC. The paper used MATLAB simulation, through increasing or decreasing the load at DC bus terminals and changing the input energy to detect the stability and reliability of the system. At the same time, the reconstruction ability of the system is tested by setting fault information for key nodes. The simulation results show that the proposed design scheme and control strategy not only maintains the stability of the bus voltage, but also makes fault isolated and achieves system reconstruction and effectively protects the storage battery.
