异步电机全阶自适应磁链观测

Asynchronous machine adaptive full—order stator flux observer

针对传统的直接转矩控制系统采用纯积分的电压模型作为磁链观测器,存在着误差积累以及直流偏移,导致电流和转矩的波动问题,提出了一种基于定子磁链的自适应全阶观测器的直接转矩控制系统。

Direct torque control uses the pure integral voltage model for torque observation. The problems of accumulate error and direct current excursions will cause the fluctuations of current and torque. A high performance sensor-less based on an adaptive full--order stator flux observer is presented.
