| 摘 要： | 为取得高性能的异步电机矢量控制,将一种基于最小二乘法在线辨识异步电机参数的方法运用到矢量控制系统中.这种基于最小二乘法异步电机参数辨识方法是在转子坐标系下进行的且不需要电机转子磁链参数,只需要定子电压、电流和转速参数.文章通过Matlab/Simulink对基于最小二乘法的参数辨识的异步电动机矢量控制系统进行了仿真,仿真结果表明:这种电机参数辨识方法能够实时更新电机控制参数,改善了矢量控制系统的性能.

| Abstract: | This paper presents a method to determine the parameters of induction machines on line so that better performance of the vector control can be achieved.The presented least-squares identification technique,which is based on a standard model of induction machines expressed in rotor coordinates,does not require the use of the rotor fluxes,but needs stator voltage and current and rotor velocity measurement.The vector control system based on the presented technique is simulated in Matlab/Simulink.The simulation ... |
