As　a　complex　dynamically　strongly　coupled　system,　DC　distribution　system　often　suffers　from　voltage　collapse　due　to　system　resonance.　In　order　to　suppress　distribution　network　resonance　and　bus　voltage　fluctuation,　this　paper　proposes　a　hybrid　control　algorithm　to　suppress　DC　distribution　system　resonance　to　further　enhance　DC　system　stability.　In　this　paper,　the　output　voltage　of　the　line　regulation　converter　(LRC)　is　the　target　of　the　study.　A　current　prediction　model　is　introduced　in　the　inner　loop　of　the　converter　control,　which　can　enhance　the　dynamic　responsiveness　of　the　system　and　eliminate　the　PWM　modulator　and　parameter　tuning,　achieve　the　unitization　of　the　inner　loop　of　the　current.　By　constructing　the　inverse　model　of　the　controlled　object,　the　outer　voltage　loop　is　unitized　under　the　control　of　two-degree-of-freedom.　The　hybrid　control　enables　the　bus　voltage　to　follow　the　reference　voltage　exactly,　which　suppresses　resonance　peaks　in　the　voltage　transfer　function　and　reduces　bus　voltage　fluctuations.　Finally,　the　proposed　hybrid　control　algorithm　is　simulated　and　verified　in　MATLAB/Simulink　platform.　The　results　show　that　the　control　strategy　can　effectively　suppress　the　resonance　and　bus　voltage　fluctuation　of　the　DC　distribution　system　and　enhance　the　dynamic　characteristics　and　anti-interference　capability　of　the　distribution　network.　Copyright　©　2023　Zheng,　Wu,　Zheng,　Liu　and　Liang.
