摘　　要：针对感应电机的能量优化问题,提出了一种基于转差率的感应电机最优效率控制方法和算法,用于恒压频比(VVVF)感应电机驱动系统,并给出仿真结果。该方法具有明显的节能效果。Induction motors Eire widely used in various places. They consume a large amount of electrical energy. That is the reason why the way of energy optimal control for induction motor is drawing our attention. This paper proposes a method--slip frequency based on optimal efficiency control of induction motor, which controls the slip frequency at different loads to make the operation efficiency optimal. This method is combined with VVYF control mode to drive the motor. The improvement of the motor efficiency is verified by the simulation result given.
