摘　　要：对异步电机的T型等效电路的数学模型进行分析与研究,提出了异步电机转矩斜坡限流起动的控制思路,并将模糊PID自适应控制思路运用在限流控制部分。在此理论基础下,利用MATLAB/Simulink工具构建仿真平台对电机转矩限流控制的软起动进行试验。试验结果说明,该方法在降低电机起动电流的同时还可以提高起动转矩,从而验证了转矩斜坡限流理论的可靠性。The mathematical model of the T-type equivalent circuit of induction motor was analyzed and studied,the control method of the asynchronous motor torque ramp current limiting was proposed,the fuzzy PID adaptive control was used in the current limiting control section. On the basis of this theory,using the MATLAB / Simulink tool to construct the simulation platform,the soft start of the motor torque limiting control was carried out. The result showed that this method could improved the starting torque of the starting current of the motor,so the reliability of the theory of the limit flow of the torque and the slope was verified.
