Optimization of hybrid energy storage system and energy management for aerial vehicles

To improve the operation efficiency and reduce fuel consumption of the hybrid energy storage system (HESS) in aerial vehicle applications, this paper proposes a modified active hybrid energy storage system construction. An automatic switch is added, such that the modified system can operate in separate or combination modes according to the power demand. In joint operation mode, an optimization-based model predictive control (MPC) energy management strategy (EMS) is designed to allocate the output power of the two energy sources. Simulation analysis and experimental validation are conducted, and results show that compared to the conventional active system, the modified HESS and the EMS improve the operation efficiency and reduce fuel consumption.
