Abstract
Surface-mount permanent-magnet synchronous motor(SPMSM) has been widely applied in accurate motion control. In this paper, the SPMSM model is divided into electrical magnetic subsystem and electrical mechanical subsystem. Then a novel error model is given by which the controllers can be designed easily. In the general PMSM controllers design, the unknown load is often neglected. In this paper, a proportional speed error is used to take the place of the unknown load without using load estimation. Based on the error model of the SPMSM, sliding mode controllers are designed to enhance the robustness of the SPMSM drive system. At last, many simulation results are given to show the effectiveness of the proposed scheme.
