Efficient Energy System Management and Control Technology

能源系统是飞行器的关键技术之一,能源系统性能的优劣对飞行器能否正常飞行及实现预定任务有重要影响。本文针对大功率飞行器对分布式循环能源系统的管理需求,开展高效能源系统管理与控制技术研究,提出一种集逐级调压控制、限流充电控制、恒流输出控制以及最大功率点跟踪(MPPT)控制为一体的层级梯次控制策略,实现分布式系统的全局优化控制和飞行器能源的功率优化调度。研制的能源管理系统(PCU)配备1条234~328 V高压母线,额定功率15 kW,电路效率大于97%,功率密度大于750 W/kg。PCU依托分布式架构,采用层级梯次控制策略,验证了高效能源系统管理与控制技术的正确性和有效性。

Energy system is one of the key technologies of aircraft. The performance of energy system has an important impact on the normal flight of aircraft and the realization of scheduled missions. Aiming at the management demands of high-power aircraft for distributed circular energy system,in this paper,a study on the management and control technology of high-efficiency energy system is carried out. A hierarchical echelon control strategy,which integrates step-by-step voltage regulation control,current limiting charging control,constant current output control,and maximum power point tracking(MPPT)control,is proposed to realize the global optimal control of distributed system and the power optimization scheduling of aircraft energy. The developed power control unit(PCU)is equipped with a 234-328 V high-voltage bus with a rated power of 15 kW,a circuit efficiency of more than 97%,and a power density of over 750 W/kg. Relying on the distributed architecture,the PCU adopts the hierarchical control strategy to verify the correctness and effectiveness of the management and control technology of high-efficiency energy system.
