Abstract
Power-electronics-based emulators have been showing promising prospects in advanced testing of electric machine applications. Typical motor emulators calculate the references of stator current in response to terminal voltages via PMSM model of the machine system,then the current behaviors of emulators are regulated by using feedback controls. However the high-frequency performances of these machine emulators could be distorted by the introduced control loops,which behave as low-pass filter (LPF),thus compromising the emulating performances. In this paper,the limits of typical motor emulators are analyzed,and a new approach is proposed for the real-time emulation of Permanent Magnet Synchronous Machines (PMSM) by using Coupling Network State Equation Control. Compared with traditional closed-loop current control,it has better high-frequency response,corresponding to a higher speed range,and also makes the simulation result closer to the real motor. In addition,this method is suitable for different forms of coupling circuits and has stronger versatility. © 2021 IEEE.
