一种利用定子电流与转子磁链点积更新感应电机转子时间常数的改进MRAS

Dot product of stator current and rotor flux can be chosen to form a model reference adaptive system (MRAS) to update the rotor time constant online in indirect-vector-controlled induction motor drives. Such a functional candidate is attractive due to the fact that its steady-state value is immune to stator resistance variation and dead-time effect. However, the stability of the estimation system ...
