High Dynamic Rotor Oriented Current Control for Permanent Magnet Synchronous Machines with Saturation Characteristics

This paper presents a new approach to adapt classic linear current control design to permanent magnet synchronous machines with saturation characteristics. All needed parameters for the current controller are online calculated from stationary machine measurements. The additional effort compared to control of linear machines is kept as low as possible in order to meet user-oriented requirements. The developed current control scheme is verified by simulation as well as by experimental results.
