摘要
基于矢量控制策略的感应电机调速是目前电气传动领域的研究热点.高性能矢量控制的关键在于转子磁场定向,而转子磁场定向的精度受电机参数变化的影响.控制系统的质量直接依赖于电动机参数测定的准确程度.为此,利用最小二乘算法实现对感应电机参数的自适应辨识方法,并用Matlab语言进行了仿真,仿真结果证明了该方法的有效性.
A present study on induction motor based on vector control is very hot in electric drive field.The key of vector control is rotor field orientation nevertheless the filedoriented performance is affected by the motor parameter.The control system's quality directly depends on the accurate degree of the motor parameter measurement.This paper introduce the solution to the parameter estimation by the use of least square method and proves its validity by Matlab simulation result.
