| 摘 要： | 提出了一种新的模型参考自适应系统（MRAS）感应电动机转速估计模型.以感应电动机本身为参考模型,以可直接测量的定子电流为状态变量,以定子电流-电压方程为可调模型,根据Popov超稳定理论提出满足全局渐进稳定的转速自适应律估计转速.利用Matlab进行仿真,仿真结果说明了模型的有效性.

| Abstract: | A novel model of model reference adaptive system(MRAS) speed estimator for induction motor is investigated in this paper.The estimator uses induction motor itself as reference model,and the direct-measuring stator current regards as state variable of reference system,selecting stator voltage-current equation as adjustable model.A speed adaption law is proposed that is used to estimate the speed based on Popov ' s hyperstable theory.Matlab is used for simulation in this article,and the results sufficiently s... |
