摘　　要：提出了一种基于事实搜索方法的新型控制策略。在工作点处(一定的转矩和转速条件下),利用该策略可以寻找到唯一的定子电压值使得电机工作于最优效率。通过仿真结果分析,论证了该控制策略的合理性。在轻载及低频工作条件下,为了减小转差率,还介绍了一种滑差补偿器的应用。A new control scheme based on search method taking advantage of the fact was proposed. At the operatingpoint （ a certain torque and speed） , there is only one value of stator voltage that operates the motor at optimum efficiency.By analyzing the simulation results, the rationality of the controller was proved. Under the light loads and low frequenciesconditions, a slip compensator was also introduced to reduce the slip.
