Permanent　magnet　synchronous　motors　(PMSMs)　are　widely　used　in　a　variety　of　fields　such　as　aviation,　aerospace,　marine,　and　industry　due　to　their　high　angular　position　accuracy,　energy　conversion　efficiency,　and　fast　response.　However,　driving　errors　caused　by　the　non-ideal　characteristics　of　the　driver　negatively　affect　motor　control　accuracy.　Compensating　for　the　errors　arising　from　the　non-ideal　characteristics　of　the　driver　demonstrates　substantial　practical　value　in　enhancing　control　accuracy,　improving　dynamic　performance,　minimizing　vibration　and　noise,　optimizing　energy　efficiency,　and　bolstering　system　robustness.　To　address　this,　the　mechanism　behind　these　non-ideal　characteristics　is　analyzed　based　on　the　principles　of　space　vector　pulse　width　modulation　(SVPWM)　and　its　circuit　structure.　Tests　are　then　conducted　to　examine　the　actual　driver　characteristics　and　verify　the　analysis.　Building　on　this,　a　real-time　compensation　method　is　proposed,　physically　matched　to　the　driver.　Using　the　volt–second　equivalence　principle,　an　input–output　voltage　model　of　the　driver　is　derived,　with　model　parameters　estimated　from　test　data.　The　driving　error　is　then　compensated　with　a　voltage　method　based　on　the　model.　The　results　of　simulations　and　experiments　show　that　the　proposed　method　effectively　mitigates　the　influence　of　the　driver’s　non-ideal　characteristics,　improving　the　driving　and　speed　control　accuracies　by　88.07%　(reducing　the　voltage　error　from　0.7345　V　to　0.0879　V　for　a　drastic　command　voltage　with　a　sinusoidal　amplitude　of　10　V　and　a　frequency　of　50　Hz)　and　53.08%　(reducing　the　speed　error　from　0.0130°/s　to　0.0061°/s　for　a　lower　command　speed　with　a　sinusoidal　amplitude　of　20°　and　a　frequency　of　0.1　Hz),　respectively,　in　terms　of　the　root　mean　square　errors.　This　method　is　cost-effective,　practical,　and　significantly　enhances　the　control　performance　of　PMSMs.　©　2024　by　the　authors.
