This paper proposes a novel technique for the dynamic output limitation of the current regulators in permanent magnet synchronous motor (PMSM) drives with either isotropic or anisotropic rotors. The saturation strategy is based on a quasi time-optimal control (QTOC) theory, which assures a very fast current response after any demanded current reference variation. Predictive current regulators have been considered, since they well fit a digital implementation. However, the proposed strategy can be easily adapted to fit for different control techniques. Simulations and experimental results are included in the paper.

Abstract
This paper proposes a novel technique for the dynamic output limitation of the current regulators in permanent magnet synchronous motor (PMSM) drives with either isotropic or anisotropic rotors. The saturation strategy is based on a quasi time-optimal control (QTOC) theory, which assures a very fast current response after any demanded current reference variation. Predictive current regulators have been considered, since they well fit a digital implementation. However, the proposed strategy can be easily adapted to fit for different control techniques. Simulations and experimental results are included in the paper.File in questo prodotto:
