一种简化的永磁同步电机转动惯量辨识方法

摘要

A simplified strategy to identify the inertia of the permanent magnet synchronous motor based upon the estimation of load torque distribution. It changed the original control condition of constringency, thus, not only to simplify the identification procedure and decrease the computation load but also ensure the accuracy of identifi-cation results. The effectiveness of this method was proved by establishment of the PMSM vector control system on the simulation platform of Matlab/Simulink.%提出了一种简化的基于扰动负载转矩估测的永磁同步电机(PMSM)转动惯量辨识策略.它改变了原有收敛控制条件,在保证辨识结果精度的情况下,简化了辨识过程,减少了计算量.在Matlab/Simulink仿真平台上搭建PMSM矢量控制系统,验证了该方法的有效性.
