本文讨论了感应电动机再生模式下自适应观测器的稳定性问题，提出了一种新的方法，即用状态空间描述误差系统。有了这个公式，它是可能的，建立一个不稳定的特征值在扭矩/速度平面的绘图，从而简化了稳定性分析。此外，一个新的稳定性准则的定义和使用的反馈增益的基础上，以及速度适应律的稳定设计。
This paper, which deals with the stability of adaptive observers for induction motor in the regenerating mode, proposes a new approach that is consist of describing the error system in state space representation. With this formulation, it is possible to establish a cartography of unstable eigenvalues in the torque/speed plane, thus simplifying the stability analysis. Moreover, a new stability criterion is defined and used to realize stabilizing designs based on feedback gain as well as on the speed adaptation law.
