| 摘 要： | 提出了新型的基于线性扩张状态观测器的感应电动机转子磁链估计模型。以两个独立的线性扩张状态观测器观测定子电流,用分别被扩张的两个状态构建闭环转子磁链观测器,根据Lyapunov稳定性理论推导满足转子磁链观测器渐进稳定的反馈增益矩阵和转速估计自适应律。利用Matlab进行了仿真,分析了电机参数变化对磁链观测和转速估计精度的影响,表明了提出的模型对电机参数变化具有强鲁棒性。

| Abstract: | A novel rotor-flux estimation model for induction motor was presented.Two independent extended state observers(ESO) were used to observe the stator current.The two extended states were combined to construct a close-loop rotor-flux observer.The feedback gain matrix and the rotor speed adaptive law were derived based on Lyapunov stability theory.The matrix could ensure that the observer is asymptotically stable.Simulation was conducted by Matlab.The effects of motor parameters variation on rotor-flux observin... |
