摘　　要：为了准确辨识永磁同步电机参数,提出一种基于变正则化参数仿射投影算法的参数辨识方法。分析d,q坐标系下的永磁同步电机数学模型,构建基于仿射投影算法的参数辨识模型,利用优化的变正则化参数仿射投影算法实现参数辨识。仿真证明,该方法能够准确辨识电机参数,优化的参数辨识方法在保证收敛速度的基础上,降低了稳态误差。In order to accurately identify the parameters of the permanent magnet synchronous motor,a parameter identification method based on the variable regularization parameter affine projection algorithm was proposed.The mathematical model of the permanent magnet synchronous motor in the d,q coordinate system was analyzed.The parameter identification model was contructed based on the affine projection algorithm.The optimized variable regularization parameter affine projection algorithm was used to realize the parameter identification.Simulation proves that the method can accurately identify motor parameters.The optimized parameter identification method reduces the steady-state error on the basis of ensuring the convergence speed.
