摘要:
针对嵌入式永磁同步电机参数辨识问题,提出一种自适应在线参数辨识方法,可在同一模型中对定子电阻、d轴电感、q轴电感和永磁体磁链进行辨识。该方法基于模型参考自适应系统,在同步旋转d-q坐标系下,构造出q轴电流自适应观测器,利用q轴电流观测误差,借助Lyapunov超稳定理论建立参数的辨识模型并推导出待辨识参数的自适应律,保证了特定条件下系统的稳定性和辨识参数的收敛性,解决了参数在线辨识算法的鲁棒性差、算法复杂等问题。仿真和实验结果表明,辨识参数能够在较短的时间内收敛到真实值附近,并且具有较小的误差。
Abstract:
An adaptive on-line parameter identification method for interior permanent magnet synchronous motor(PMSM) is presented in the paper.The rotor resistance,d-axis inductance,q-axis inductance and permanent magnet flux are achieved at the same time in the presented model.Based on model reference adaptive system,an adaptive q-axis current estimator for interior permanent magnet synchronous motor is put forward in the rotor reference frame.And the q-axis current error is used to obtain the adaptive laws of parame...
