Application of Different Numerical Integration Methods for Discrete MrasCC Estimator of Induction Motor Speed - Comparative Study

This article deals with the application of different numerical integration methods for discretization of the current-based MRAS
^CC
estimator of the induction motor speed. It is shown that Modified Euler method ensures much greater stable solution for the analyzed speed estimator then conventional Euler methods, and the obtained solution is close to the discretization using much more complicated Tustin method. The suitable simulation results are presented in the article.
