摘　　要：随着大功率电推进负载、通信载荷时分多址工作模式等大量使用,对卫星能源系统阶跃响应要求越来越高。为了减少阶跃负载对母线电压尖峰的影响,提出了一种基于预测控制的卫星能量管理策略,该策略基于能量守恒原则预测电流变化趋势,从而进一步提高母线的动态响应能力。通过系统级仿真验证了该算法的有效性。With high-power electric load and communication load of working in Time Division Multiple Access mode used in great quantities,such load step requires high dynamic response of satellite power systems.In order to reduce the influence of step load on bus voltage spike,an energy management strategy based on predictive control was proposed.This strategy was based on the energy balance principle to predict current trends,so as to further improve the ability of the dynamic response of the bus.The effectiveness of the proposed algorithm was verified by the system level simulation.
