摘要
针对永磁同步电动机参数的时变和不确定性,设计了基于遗忘因子递推最小二乘法的电机定子电阻、dq轴电感以及转动惯量的辨识方法,仿真结果表明了该方法收敛速度快,能准确地实现电机定子电阻、dq轴电感以及转动惯量的辨识。
For the time-varying and uncertainty of permanent magnet synchronous motor(PMSM) parameters, a identification method for stator resistance, inductance of dq axle and rotational inertia of motor was designed based on FFRLS. Simulation resuh shows that the value of the stator resistance,inductance of dq axle and rotational inertia can be identified precisely with the identification method which has a fast convergence rate.
