Determinación de la Posición Angular de Motor de Reluctancia Conmutada MFR132.5 con Estimador de Horizonte Deslizante

Abstract

The measure of the instant angular position of the rotor is integral part of the control of Switching Reluctance Motors (SRM) drivers. The direct measurement of this variable adds complexity and cost to the system and it doesn’t give good results sometimes. That has motivated the development and test of estimators for the rotor angular position that only use the measurements of the electrical variables of the SRM. In this work are presented two variants of a Moving Horizon Estimator (MHE) for estimating the speed and rotor angular position of the SRM MFR 132.5. Each variant uses a different model of the motor, a white box model and a grey box model, both of them presented in this paper too. It was carried out the simulation on PC of the designed estimators for estimating the speed and the angular position of the rotor in three tests under different conditions and considering an error in the initial estimation of the angular position and noisy measurements. The results show that this kind of estimator gives good estimations, which are better if a grey model of the system is used.
