For the long-endurance stratospheric airship to operate safely and dependably, the energy system’s stability is crucial. The stability issue is particularly noticeable for energy systems with several buses and converters connected in series and parallel. In order to establish a semi-regulated busbar mode, this paper suggests a new stratospheric airship energy system structure based on a three-port converter. It also examines the stability of the complex energy system made up of multiple converters and semi-regulating double-bus under various load impedances. The input and output impedances of the energy system under various subsystem division techniques are first determined by creating an impedance model of a stratospheric airship that contains solar cells, batteries, and different converters. Then, the stability of the energy system is analyzed using the stability criterion of the impedance ratio of the multi-bus direct current system, the theoretical analysis results are verified by simulation experiments. Finally, a hierarchical control method of airship energy system based on consistent power coordination control and Sliding mode control is proposed. According to simulation data, this technique can improve the airship energy system’s stability.
