摘要
定子电阻的变化影响异步电机矢量控制系统的性能。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 an induction motor has impacts on the performance of a vector control system.A simple construction estimator for stator resistance identification was designed based on the fuzzy control theory.On the basis of this and according to the vector control theory,Simulink in Matlab was adopted to design the induction motor vector control system.The simulation result shows that the stator resistance of identification has smaller error and the system responds fast with small torque ripple and good robustness.
