Abstract

This paper proposes an improved PLL-type estimator for self-sensing control based on back-electromotive force (back-EMF) estimation in an interior permanent magnet synchronous motor (IPMSM). Although the position and speed of rotor are accurately estimated by PLL-type estimator in steady state, the estimated information in transient state may be unstable. To analyze the transient performance of rotor position estimators, the structure design and proposed methods of estimator are introduced. And, the effect of proposed method has been figured out that the estimated speed error and torque ripple are decreased in transient state. The feasibility of the introduced estimator effect are verified through simulation results.
