摘要

本文提出了一种间接矢量控制异步电动机起动的自整定方法。该调谐算法是基于异步电动机转子磁链特性的逐步转矩指令。在进行整定时,考虑了转子磁链不理想变化引起的暂态电机端电压中出现的感应电机定子铁心损耗的影响。该方法可以精确地调谐转子时间常数的逆。实验室模型系统的仿真结果验证了所提自整定方法的有效性。

An auto-tuning method for vector controlled induction motor drives considering stator core loss
This paper presents an auto-tuning method for the indirect vector controlled induction motor drives for the start up. The tuning algorithm is based on the rotor flux behavior of the induction motor for a stepwise torque command. An effect of the stator core loss of the induction motor, which appears in the transient motor terminal voltage caused by the undesirable rotor flux variation, is taken into account when the tuning is implemented. This method can tune the accurate inverse of the rotor time constant. Simulation results of the laboratory model system verify the validity of the proposed auto-tuning method.
