摘要
Abstract
To address the issues of insufficient bus voltage stability and limited response capability in deep space probe,a dual-power bus topology is designed based on collaborative control of po-wer supply system and electric propulsion power.Based on this topology,a bus voltage control strategy using a back propagation(BP)neural network proportional-integral(PI)is proposed.The BP neural network is utilized for online tuning of the voltage loop PI controller and the in-ductor current PI controller to regulate the bidirectional Buck/Boost circuit.Two operating modes are simulated to verify the effectiveness of the control strategy.The results confirm that the control strategy achieves excellent power bus voltage tracking capability and efficient overall power distribution for the power supply system.The proposed control strategy is applicable to various high-power probes or constellations equipped with electric propulsion power.关键词
