Parameter Adaptation Modeling and Simulation of Permanent Magnet Synchronous Motor

为准确辨识永磁同步电机模型参数,提出一种辨识系统模型方法实现对电机参数的估算。基于Popov超稳定理论,提出自适应参数和参数自适应律的设计方法,给定参考条件下建立矢量控制下的自适应参数辨识模型,通过MatLab软件进行仿真。结果表明,理论值比较接近建立模型得到的参数辨识值,且辨识结果相对准确。

In order to identify the model parameters of permanent magnet synchronous motor accurately,a method of identifying system model is proposed to estimate the parameters of the motor.Based on Popov exceed stable theory,put forward the adaptive parameters and design method of adaptive law,under the condition of a given reference in adaptive parameter identification model of vector control,through the MatLab software simulation,the results show that the theoretical value is close to the model parameter identification of values,and the identification result is relatively accurate.
