摘要:

为了提高直接力矩控制系统中定子磁链的观测精度,提出了一种新的定子磁链自适应观测器。该观测器在观测定子磁链的同时也辨识了随温度变化的定、转子电阻。该观测器的稳定性利用波波夫理论进行了严格的证明,其鲁棒性和观测效果也通过数字仿真得到充分的证实。

Abstract:

In order to improve the observing precision of the stator flux observer of DTC systems, a new adaptive stator flux observer is proposed.With this flux observer, the stator resistance and rotor resistance, which vary with motor temperature, are identified simultaneously.

Key words: DTC, induct ion mo to r, adap t ive stato r flux observer, parameter ident ificat ion
