文摘The main difficulty in designing predictive controllers for permanent magnet motors with different topologies is the control of the additional current subspaces.The frequency of current components in these additional subspaces(harmonic subspaces and zero-sequence loop/subspaces)is several times the fundamental current frequency.Moreover,the inner voltage source would vary with operation conditions,and there are also different views about the causes of inner voltage sources.This paper analyses the inner voltage sources in these additional current subspaces for permanent magnet motors with different drive topologies using simulation and experiment.Based on the results of the simulations and experiments,we analyze the sources and characteristics of the inner voltage sources and provide a predictive model calibration method for the components in these additional subspaces.Finally,the deadbeat current control scheme based on calibrated look-up table is designed and verified.
