  • unified direct flux vector control for Ac Motor drives
    IEEE Transactions on Industry Applications, 2011
    Co-Authors: G. Pellegrino, Radu Bojoi, Paolo Guglielmi
    Abstract:

    This paper introduces a unified direct-flux vectvector control scheme that is suitable for sinusoidal Ac Motor drives. The Ac drives considered here are induction Motor, synchronous reluctance, and synchronous permanent-magnet (PM) Motor drives, including interior and surfAce-mounted PM types. The proposed controller operates in stator flux coordinates: The stator flux amplitude is directly controlled by the direct voltage component, while the torque is controlled by regulating the quadrature current component. The unified direct-flux control is particularly convenient when flux weakening is required since it easily guarantees maximum torque production under current and voltage limitations. The hardware for control is standard, and the control firmware is the same for all the Motors under test with the only exception of the magnetic model used for flux estimation at low speed. Experimental results on four different drives are provided, showing the validity of the proposed unified control approAch.

  • Unified Direct-Flux Vector Control for Ac Motor drives
    2010 IEEE Energy Conversion Congress and Exposition, 2010
    Co-Authors: G. Pellegrino, Radu Bojoi, Paolo Guglielmi
    Abstract:

    The paper introduces an Unified Direct-Flux VectVector Control (UDFVC) scheme suitable for simusoidal Ac Motor drives. The Ac drives considered here are the Induction Motor (IM) drives, Synchronous Reluctance (SyR) and synchronous Permanent Magnet (PM) drives of the Interior PM (IPM) and SurfAce-mounted PM (SPM) types. The proposed controller operates in stator flux coordinates: the stator flux amplitude is directly controlled by the direct voltage component, while the torque is controlled by regulating the quadrature current component. The control firmware is the same for all the Motor under test with the only exception of the magnetic model used for flux estimation at low speed. The UDFVC is particularly convenient when flux-weakening is required, since it easily guarantees maximum torque production under current and voltage limitations. Experimental results on four different drives are provided.

  • compensation of dead time effects based on adaptive harmonic filtering in the vector controlled Ac Motor drives
    IEEE Transactions on Industrial Electronics, 2007
    Co-Authors: Song Young Kim, Seungyub Park
    Abstract:

    A new dead-time compensation method for vector-controlled Ac Motor drives is proposed. The method only compensates the fundamental and sixth harmonic component of the inverter-output distortions in synchronous reference frame. The fundamental component is compensated by feedforwardly adding a predetermined compensation signal to the voltage reference of Ac Motor drive. To compensate the harmonic distortions, the harmonic compensator with all-pass-based adaptive bandpass filter is proposed and builds up the feedbAck loop with current controllers in order to minimize the distortions due to dead-time effects. The method is software intensive and independent of the polarity of the phase currents and nonlinear-switching charActeristics varied with operating conditions of the inverter. It is simulated and implemented on a 750-W laboratory Ac Motor drive, where its effectiveness is verified
