The　LC　filter　is　effective　to　reduce　the　high-frequency　current　harmonics　of　permanent　magnet　synchronous　motor(PMSM),　the　performance　of　which　differs　from　the　system　without　filter　and　is　also　greatly　affected　by　the　current　loop　PI　parameters.　In　order　to　improve　the　performance　of　the　inverter　side　current　feedback　control　system,　a　multi-objective　optimization　design　method　for　the　current　loop　PI　parameters　is　proposed.　The　open　loop　transfer　function　of　the　current　loop　with　the　inverter　side　current　feedback　is　derived,　and　the　influences　of　the　current　loop　parameters　on　the　system　stability,　dynamic　performance,　bandwidth　and　resonant　peak　value　are　analyzed.　Furthermore,　the　bandwidth,　overshoot　and　resonance　peak　are　determined　as　the　optimization　objectives,　and　their　constraints　are　given.　Moreover,　the　current　loop　parameters　are　solved　by　the　genetic　algorithm.　The　system　simulation　is　carried　out　based　on　the　designed　current　loop　parameters,　and　the　performance　is　compared　with　that　of　the　two　traditional　design　methods.　The　simulation　results　verify　the　proposed　method.　Compared　with　the　traditional　methods,　the　multi-objective　optimization　method　can　reduce　the　overshoot,　resonance　peak　and　high-frequency　current　harmonics,　and　improve　the　current　loop　bandwidth　and　current　tracking　capability.　©　2023　Editorial　Office　of　Journal　of　Electrical　Engineering.　All　rights　reserved.
