摘要

本文分析了异步电动机速度估计器的离散化实现。测试了离散化方法的类型对该估计器稳定范围的影响。本文考虑了三种最常用的离散化方法:前向欧拉法、后向欧拉法和Tustin法。测试了离散化步长对估计器稳定性的影响，确定了估计器稳定性的速度极限。仿真结果验证了整个分析在磁场定向控制的感应电机驱动的大范围转速变化下，离散步长各值的正确性。

Discrete realization of MRAScc estimator of induction motor speed using analogue emulation

In this paper the discrete realization of MRAScCestimator of the induction motor speed is analyzed. The influence of the type of the discretization method on the stability range of this estimator is tested. Three most popular discretization methods have been taken into account: the forward and backward Euler methods and the Tustin method. The influence of the discretization step is tested and the speed limit for the estimator stability is determined. Entire analysis is validated by simulation results in wide range of speed variation of induction motor drive, which was controlled by a field-oriented method, for various values of the discretization step.
