Abstract：

This　paper　presents　a　novel　V/f　controlled　induction　motor　for　improvement　of　speed　characteristics.　The　proposed　method　is　an　auto-boost　voltage　method　to　compensate　the　voltage　drop　of　stator　impedance　and　a　slip　frequency　compensation　method　to　decrease　the　speed　error　caused　by　the　change　of　load.　The　operating　region　of　proposed　method　is　discussed　by　using　vector　locus.　The　stability　of　the　proposed　system　is　analyzed　by　using　root　locus.　In　motoring　mode　and　regenerating　mode,　steady-state　characteristics　and　transient　responses　of　V/f　control　method　are　investigated　by　experimental　system.
