Electricity is the main type of energy consumed by industry. Awareness of opportunities for reducing electrical consumption has brought an emphasis on electrical energy saving for research such as in power electronics. This paper proposes an energy optimized control using fuzzy logic for induction motors based on noninstrusive efficiency estimation. The presented control is viewed as a direct energy saving technique since it takes into account both the input and output powers of the induction motor, through feedback of the efficiency estimate.
