Loss-model-based efficiency optimization control for asynchronous motor using fuzzy-logic

It is estimated that more than 50% of the world electric energy generated is consumed by electric machines. In face of the dual-pressure of energy shortage and environmental degradation, it is a burning question to improve the running efficiency of electric motors. In this paper, the relationship between the minimal loss and the flux of asynchronous motor is studied, and based on this, a loss model based fuzzy logic control strategy is adopted to realize efficiency optimization control for asynchronous motor. Simulation results show that the proposed control method can minish motor loss effectively, and it has feasibility and effectiveness on energy saving for motors.
