摘　　要：针对基于稳态等效电路图的感应电动机转差频率控制系统有大马拉小车的现象,引用了感应电动机最优转差模型,提出了一种感应电动机转差频率最优效率控制系统。并与传统感应电动机转速闭环转差频率控制进行比较,通过仿真与实验研究,结果表明该系统具有良好的效率优化效果。Tradition induction motor control system always keeps the flux constant, which makes the efficiency very low. The optimize slip-frequency was used to improve this condition. The slip frequency was controlled at different loads to make the operation efficiency optimize. Compared with the traditional slip frequency control, the simulating and experiment results show that the system has better efficiency optimization
