General Algorithm of Stator and Rotor Resistance and Speed Estimate

为了抑制参数变化对感应电机交流调速系统性能带来的影响,依据模型参考自适应理论,分别对无速度传感器和有速度传感器矢量控制系统进行速度和定转子电阻同时估计,推导出模型参考自适应估计的一般算法。仿真结果表明,估计算法能对速度和定子电阻和转子电阻进行准确快速地估计,且具有较强的鲁棒性。通用估计算法准确,且正确的。

In order to reduce the influence of the variation of parameters on induction motor drives, according to the theory of mode reference adaptive system （MRAS）, firstly simultaneously estimate stator resistance and rotor speed of sensorless induction motor drives, secondly simultaneously estimate online stator and rotor resistance of induction motor with speed-sensor. Finally, Simulation results are presented. And they show the method of this paper is correct.
