摘要 在异步电动机的矢量控制中,需要准确地估计出电机的磁链,通常所用的纯积分方法对异步电机磁链的估计会带来很大误差.通过对异步电动机稳态模型的分析提出了一阶惯性加补偿的方法来代替纯积分算法.利用该算法可以有效估计出异步电动机定子磁链.该算法计算简便,对硬件要求不高,非常适用于高性能的通用异步电动机控制. The steady state model of induction machine is analyzed and a new method of induction machine stator flux estimation is presented using one-order inertia with compensating method instead of pure integration of back EMF method to estimate stator flux of induction machines. The new method is simple less hardware is required, and is suitable for high performance control of induction machines.
