摘要
本文以异步电动机矢量控制原理为基础,研究基于MRAS的无速度传感器矢量控制系统。介绍一种改进型电压模型转子磁链观测方案,采用Matlab/Simulink软件进行了仿真实验。实验结果证明该方法能够较准确地估算转子磁链和转速,系统运行良好。
Based on principle of vector control of induction motor, the paper analyzed model reference adaptive control system, and introduced a modified voltage model rotor flux observation scheme, performed experiments with Matlab/Simulink. The results confirmed that the scheme could estimate the rotor flux and speed precisely, the running condition of system was favorable.
