Active　damping　is　critical　to　suppress　resonance　for　LC-filtered　permanent　magnet　synchronous　motor　(PMSM),　and　capacitor　current　feedback　(CCF)　is　commonly　used　due　to　the　simple　implementation　and　good　damping　effect.　However,　the　slow　response　and　extra　sensors　are　the　shortages　of　the　original　CCF　damping.　This　article　proposes　a　novel　CCF　damping　control　scheme　to　significantly　enhance　both　damping　effect　and　dynamic　response　without　additional　sensors,　in　which　two　improvements　are　presented.　One　is　the　introduction　of　a　negative　coefficient　low-pass　filter　(LPF)　in　parallel　with　the　traditional　CCF　loop,　which　can　reduce　the　low-frequency　gain　while　ensure　medium　and　high-frequency　gains　of　the　CCF　loop,　thus　decreasing　the　resonance　peak　while　improving　the　open-loop　cutoff　frequency.　The　other　is　the　proposed　current　reconstruction　with　extended　state　observer　(ESO),　which　can　estimate　motor-side　currents　and　filter　capacitor　currents　with　simple　design　and　high　accuracy,　hence　realizing　the　LPF-CCF　active　damping　independent　of　additional　sensors.　The　stability,　accuracy,　robustness,　as　well　as　steady-state　and　dynamic　performance　of　the　proposed　damping　scheme　are　analyzed.　The　experimental　results　about　a　1.1-kW　PMSM　are　provided　to　verify　the　effectiveness　of　the　proposed　ESO-LPF-CCF　scheme.　IEEE
