| Abstract: | In a conventional induction machine, operation under rated conditions is highly efficient. However, at torques and/or speeds far from the rated values the efficiency is greatly reduced. Efficiency optimization of inverter-fed induction motor drives has significance for saving energy, cooling system and controlling environmental pollution. This paper overviews various efficiency optimization control strategies on variable speed induction motor drives presented recently years. The existing efficiency optimization control strategies are divided into optimal flux control based on model, on-line research of minimum input power and minimum stator current control etc. The performances of various efficiency optimization control strategies are analyzed. Some further research directions and efficiency optimization control result with good dynamic performance are presented. |
