摘　　要：实现对永磁同步电机调速系统高性能控制的基础是准确的数学模型和电机参数,其中电感参数、定子电阻和永磁体磁链对电机的稳态和动态运行性能影响较大,这会降低矢量控制的有效性。考虑到定子电流引起的磁路饱和及交叉饱和效应的影响以及运行过程中温度等其他因素的影响,以内置式永磁同步电机为研究对象,在矢量控制系统的基础上,采用模型参考自适应控制系统(MRAS)在线辨识电机参数,并通过MATLAB/Simulink仿真验证其有效性。The achievement of high-performance speed control in permanent magnet synchronous motor systems relies on accurate mathematical models and motor parameters.The inductance parameters,stator resistance,and magnetomotive force of the permanent magnets significantly impact the steady-state and dynamic operating performance of the motor,thereby affecting the effectiveness of vector control.This study considers the effects of magnetizing flux saturation,crosstalk due to stator current,as well as other operational factors such as temperature.It focuses on an internally excited permanent magnet synchronous motor as its research subject and utilizes a model reference adaptive system(MRAS)within the vector control system to online identify motor parameters in real time.The validity of this approach is confirmed through simulation using MATLAB/Simulink.
