Research on Multi-objective Optimization Methods for Aircraft Energy Conversion System Control Unit

This paper takes the electric power system of more-electric aircraft as the research object, analyzes the future power topology, energy transmission, and usage characteristics of more-electric aircraft, and presents an optimized design scheme and control strategy for the aircraft power system based on energy storage. Combining application scenarios, an optimization algorithm model for the power system is constructed, and multi-objective optimization is performed on the control strategy. Simulation analysis shows that the energy optimization and integrated management of the aircraft power system based on the complementary operation mode of energy storage and generator have a good effect on improving the energy utilization efficiency of the aircraft and reducing the bus current fluctuation. It has potential application value in engineering practice, which can support the improvement of aircraft economy and the realization of long-range flight.
