The Online Estimation Method of Stator and Rotor Resistance of Induction Motor Based on Neural Network

矢量控制是一种对电机参数依赖性很强的控制方法，本文采用了神经网络辨识非线性系 统的思路，提出一种电机定、转子电阻参数的在线估计方法，用于电压控制型矢量解耦控制系统 中，可以基本消除电机参数变化对系统控制性能的影响，并通过仿真验证了该方法的可行性和有 效性。

The performance of vector control heavily dependson the Parameters of the induction motor. An online estimation method of stator and rotor resistance of induction motor has been proposed which based on the method of identification nonlinear system using neural network. If the online estimation method is applied in vector decoupling control based on voltage equation, the influence of the parameter variation of the in- duction motor can be resolved. The simulation results show the feasibility and validity of the method.
