摘要
随着现代电力电子技术的迅速发展,永磁电机在控制调速性能方面的优势也逐步凸显,这使得永磁电机在各个领域的应用范围也随之拓宽。然而,在电机运行过程中因参数变化而产生的误差时时影响着控制精度,此时,对参数进行在线辨识成为提高系统性能的保证。在传统参数辨识的基础上提出了一种改进型的永磁电机参数辨识算法。
With the rapid development of modern power electronic technology,the advantages of permanentmagnet motor in controlling speed control performance was gradually becoming more prominent,which make theapplication of permanent magnet motor in various fields be widened. However,the error caused by the variation of theparameters in the operation of the motor is always affected the accuracy of the control,and the on-line identification ofthe parameters is the guarantee of improving the system performance. An improved permanent magnet motorparameter identification algorithm was proposed based on the traditional parameter identification.
