摘要
对需要异步电动机恒功率运行的应用领域,特别是电动汽车这种需要大范围扩速运行的情形,弱磁控制是一个非常重要的方法。基于矢量控制提出一种恒交轴电压弱磁控制方法,该方法与电机参数无关,稳定性强,实现简单,试验结果验证了该方法的正确性和有效性。
The field weakening control is important for the induction motor＇ s constant power operation that is required by the electric vehicle. Based on the detailed theoretical analysis, using the vector control, a constant q-axis stator voltage field weakening control method that is stable, independent of motor parameters is presented. Its validity is proved by experimental results.
