摘要：异步电机无速度传感器矢量控制系统是目前研究的热点，本文采用全阶自适应状态观测器，在传统的PI自适应律的基础上，加入了模糊自适应PI控制策略，对转速进行估计。最后，通过MATLAB仿真数据对比，得出改进型的全阶自适应状态观测器速度辨识系统对电机定、转子电阻变化的鲁棒性增强的结论。

Abstract: The vector control system of the induction motor speed sensorless is a focus on the current research. On the basis of traditional PI adaptive law, we use the full-order adaptive state observer, adding the strategy of the fuzzy adaptive PI control, in order to estimate the motor&rs
