摘要:
针对永磁同步电机(PMSM)无位置估算算法复杂,易受干扰的问题,提出一种基于滑模观测器(SMO)来预估转子位置和速度的新方法。通过对静止坐标系下反电势(EMF)分量的估算,提取了转子位置信息,采用锁相环(PLL)的方法得到转子位置和速度,补偿了角度预估中产生的相位滞后,构建了Lyapunov函数证明滑模观测器的收敛性,解决了无位置预估算法中鲁棒性差、算法复杂的问题。通过建立PMSM全数字无位置传感的矢量控制系统平台,对该方法做了详细验证。实验结果表明:该方法解决了系统在暂态下估算转子位置不准确且容易受到干扰的问题,具有很好的鲁棒性,预估转子位置准确且易于工程实现。
Abstract:
For traditional sensorless algorithm of permanent magnet synchronous motor(PMSM) is of complexity and disturbance,a novel way to estimate the rotor position and speed of PMSM based on sliding mode observer(SMO) is presented.Through estimating the electromotive force(EMF) in the stationary reference frame,the rotor position and speed were gained by the phase lock loop(PLL),which were contained in the EMF;and this method compensated for the phase lag caused by the angle estimation.Then a Lyapunov function was...
