An improved stationary-frame-based current control scheme for a permanent-magnet synchronous motor

An improved stationary-frame-based current control scheme for a permanent-magnet synchronous motor (PMSM) is presented. To improve the current control performance in the stationary frame, the disturbance is estimated using the time-delay control. The proposed scheme is implemented on a PMSM using digital signal processor TMS320C31 and the effectiveness is verified through the comparative experiments.
