Abstract	In order to improve the rotor position estimation performance of position sensorless interior permanent magnet synchronous motor (IPMSM) control system in the dynamic situation, a full-order sliding-mode observer (SMO), of which the state variables were current and extended electromotive force (EEMF), was analyzed in this paper. Then, based on the EEMF model of IPMSM, a full-order state equation in the stationary reference frame was established. On the basis of Lyapunov analysis, a simplified method of designing the feedback gain matrix was presented. And the relationship between the parameters of the feedback-gain matrix and the dynamic response performance was studied specially. Experimental results demonstrated the feasibility of the full-order SMO with a position sensorless IPMSM control system.
