Abstract
The present disclosure relates to a dead-time compensation method and apparatus for a permanent magnet synchronous motor (PMSM), a device, and a storage medium. The method includes: acquiring current sampling time d-axis currents and current sampling time q-axis currents corresponding to current sampling time three-phase stator currents of the PMSM; acquiring, according to vector angles of current sampling time three-phase current vectors, current sampling time filtered d-axis currents, and current sampling time filtered q-axis currents, included angles between the current sampling time three-phase current vectors and the d-axis, and acquiring current sampling time angles θ of the current sampling time three-phase current vectors; acquiring polarities of the current sampling time three-phase stator currents according to the current sampling time angles θ; and acquiring current sampling time compensation voltage values according to the polarities of the current sampling time three-phase stator currents.
