| Abstract |
The paper deals with the analysis of PMSM drive system with different speed and position observers. Three methods of speed and position estimation were described and compared. The first method is based on voltage differential equations of PMSM and the second one uses the reduced-order observer of Luenberger type. The third method uses the full-order extended observer The mathemati-cal model of the vector-controlled drive system in Matlab-Simulink was used for simulation. All the estimation methods were compared and evaluated from the point of view of model sensitivity to the stator parameter changes and the less sensitive methods were tested in the experimental vector con-trolled PMSM drive system. Average speed and position estimation errors as well as dynamical prop-erties of the simulated and real drive system were tested and evaluated in the presence of errors of motor parameter used in the estimator models. |
