摘要
定子电阻的变化对异步电机矢量控制系统的性能具有重要的影响,准确获取定子电阻值在高性能电机控制系统中具有十分重要的意义。本文基于模糊控制理论,设计了一种结构简单的模糊定子电阻辨识器。在此基础上,根据矢量控制理论,采用Matlab/Simulink软件设计了异步电机矢量控制系统。仿真结果表明,辨识的定子电阻误差较小,系统响应迅速、转矩脉动小、鲁棒性好。
The change of stator resistance of induction motor has an important implication in vector control system.Accurate acquisition of stator resistance of induction motor plays a significance part in high-performance motor control systems.A simple construction estimator for stator resistance identification has been designed based on fuzzy control theory in this paper.And then,the induction motor vector control system is designed using Matlab/ Simulink software according to the vector control theory.The simulation result shows that the system consisting of the estimator boasts a fast response,small torque ripple and good robustness.
