摘要
针对电机调速系统中使用较多的三相交-直-交电压型逆变器供电的直接转矩控制系统中转矩脉动、磁链脉动较大等诸多问题,提出采用三电平逆变器供电的直接转矩控制方案,可以为定子磁链矢量幅值以及相位控制提供更多的控制自由度,从而有效解决转矩、磁链脉动等问题,并在试验基础上,对整个控制系统的工作原理进行介绍。
Aiming at the motor speed regulation systems used more three intersecting-straight-into the voltage type inverter power supply direct torque control system transfer torque ripple,magnetic chain pulsation larger such problems,the three-level inverter power supply of DTC scheme was proposed.Such obvious for stator flux vector amplitude and phase control to provide more control freedom,thus effectively solve the torque ripple and flux.And on the basis of experiment to the whole control system introduced the work principle.
