Abstract :
In this paper, the speed regulation problem for permanent magnet synchronous motor (PMSM) systems under vector control framework is studied. A modified composite control strategy combining model reference adaptive control (MRAC) method and extended state observer (ESO) technology, called MRAC+ESO method, is proposed. Controller is designed for the speed loop of the permanent magnet synchronous motor (PMSM) to improve the performance of the system. The stability analysis, simulation and experimental results are presented to show the effectiveness of the proposed control method.
