Field-oriented　control　(FOC)　is　a　preferred　control　method　for　induction　motors.　The　purpose　of　FOC　is　to　guarantee　perfect　dynamic　and　steady　performance　of　induction　motors,　but　there　is　cross-coupling　between　dq　current　components,　which　impairs　the　characteristics　of　response.　Therefore,　a　decoupled　current　control　strategy　using　internal　model　based　on　active　disturbance　rejection　control　(ADRC)　is　proposed.　The　internal　model　control　(IMC)　is　used　to　control　an　ideal　motor　decoupled　model,　which　is　directly　related　to　the　system　dynamic　response　performance.　The　ADRC　is　used　to　estimate　and　compensate　the　disturbances　so　that　it　reduces　the　reliance　of　IMC　on　the　time　constant　of　filter　when　the　model　mismatches.　The　proposed　method　has　great　contribution　to　the　robustness　of　parameter　uncertainties　and　disturbances.　The　experimental　results　indicate　that　the　robustness　of　the　proposed　optimal　design　method　for　IMC　is　better　than　the　conventional　IMC　when　the　disturbances　occur　and　the　model　mismatches,　and　the　method　is　feasible　and　effective.　©　2016　The　Institute　of　Electrical　Engineers　of　Japan.
