摘要
对永磁同步电动机控制系统逆变开关的死区效应进行分析。利用平均电压误差补偿法来补偿死区效应,并针对电流零位钳位现象,对平均误差电压补偿法进行改进,采用交、直轴电压来判断定子电流扇区并选择误差补偿电压分量的方法来补偿死区效应产生的定子电流畸变。
This paper studied on the dead-time effect for the inverter of permanent magnet synchronous motor servo system. A novel method was proposed for dead-time effect compensation basing on average error volt- age. The d-axis （direct） voltage and q-axis （quadrature） voltage were used to determine the sector of the stator current, and compensated voltage was selected to compensate the stator current distortion causing by the dead-time effect.
