Abstract

A novel energy-optimized control strategy for induction motors based on the advanced nonintrusive efficiency estimation is proposed in this paper. The two enabling techniques for the efficiency estimation are spectral estimation that detects rotor speed from rotor slot harmonics in the stator current and accurate signal-injection-based stator resistance estimation. For the implementation of the control strategy, fuzzy logic control is used to process the efficiency estimate feedback. The simulation result is presented to verify the proposed control.
