基于定子电流的MRAS转速估计方案

摘要

在传统的模型参考自适应估算转速的基础上，将参考模型变为感应电机本身，即通过感应电机的定子电流构造转速辨识模型。该方法对电机参数依赖比较小，不含纯积分环节。通过MATLAB/Simulink对系统进行仿真。结果表明，该方法具有较高的转速辨识精度。%Based on the traditional model reference adaptive system used on the speed estimator, the induction motor was used as the reference model, namely the speed identification model created through the stator current of the IM. This method has little reliant to the motor parameters, and does not contain any integrator system. The system was simulated in MATLAB/Simulink, and the result showed that the method had highly accuracy of the speed identification.
